Percentages Worksheets

Welcome to the percentages math worksheet page where we are 100% committed to providing excellent math worksheets. This page includes Percentages worksheets including calculating percentages of a number, percentage rates, and original amounts and percentage increase and decrease worksheets.

As you probably know, percentages are a special kind of decimal. Most calculations involving percentages involve using the percentage in its decimal form. This is achieved by dividing the percentage amount by 100. There are many worksheets on percentages below. In the first few sections, there are worksheets involving the three main types of percentage problems: calculating the percentage value of a number, calculating the percentage rate of one number compared to another number, and calculating the original amount given the percentage value and the percentage rate.

Percentage Calculations

percentage homework

Calculating the percentage value of a number involves a little bit of multiplication. One should be familiar with decimal multiplication and decimal place value before working with percentage values. The percentage value needs to be converted to a decimal by dividing by 100. 18%, for example is 18 ÷ 100 = 0.18. When a question asks for a percentage value of a number, it is asking you to multiply the two numbers together.

Example question: What is 18% of 2800? Answer: Convert 18% to a decimal and multiply by 2800. 2800 × 0.18 = 504. 504 is 18% of 2800.

Calculating what percentage one number is of another number is the second common type of percentage calculation. In this case, division is required followed by converting the decimal to a percentage. If the first number is 100% of the value, the second number will also be 100% if the two numbers are equal; however, this isn't usually the case. If the second number is less than the first number, the second number is less than 100%. If the second number is greater than the first number, the second number is greater than 100%. A simple example is: What percentage of 10 is 6? Because 6 is less than 10, it must also be less than 100% of 10. To calculate, divide 6 by 10 to get 0.6; then convert 0.6 to a percentage by multiplying by 100. 0.6 × 100 = 60%. Therefore, 6 is 60% of 10.

Example question: What percentage of 3700 is 2479? First, recognize that 2479 is less than 3700, so the percentage value must also be less than 100%. Divide 2479 by 3700 and multiply by 100. 2479 ÷ 3700 × 100 = 67%.

The third type of percentage calculation involves calculating the original amount from the percentage value and the percentage. The process involved here is the reverse of calculating the percentage value of a number. To get 10% of 100, for example, multiply 100 × 0.10 = 10. To reverse this process, divide 10 by 0.10 to get 100. 10 ÷ 0.10 = 100.

Example question: 4066 is 95% of what original amount? To calculate 4066 in the first place, a number was multiplied by 0.95 to get 4066. To reverse this process, divide to get the original number. In this case, 4066 ÷ 0.95 = 4280.

Percentage Increase/Decrease Worksheets

percentage homework

The worksheets in this section have students determine by what percentage something increases or decreases. Each question includes an original amount and a new amount. Students determine the change from the original to the new amount using a formula: ((new - original)/original) × 100 or another method. It should be straight-forward to determine if there is an increase or a decrease. In the case of a decrease, the percentage change (using the formula) will be negative.

Resources And Tools

Calculating percentage.

Step 1 Put the two...

• A simple way to multiply a decimal by 100 is to move the decimal to the right two digits. • The percent symbol is then just tacked on at the end, like a unit of measurement would be.

Step 4 Bonus Example 1:

  • There are 12 months total in a year, so Jerry worked 7/12 months.
  • Then, convert the fraction to a decimal: 7/12 = 0.58
  • Next, convert the fraction to a percent: 0.58 x 100% = 58%
  • Jerry the electrician worked 58% of the year.

Step 5 Bonus Example 2:

  • 35 correct answers + 10 incorrect answers = 45 answers total
  • We can set this problem up as the fraction 35/45.
  • 35/45 = 0.78
  • 0.78 x 100 = 78%
  • Donovan got 78% of the answers correct on his test.

What Is X Percent of Y?

Step 1 Use this method when you’re given a percentage and a “whole.”

You can also simply move the decimal to the left two places.

Step 3 Cross multiply...

  • In this example, $0.45 is the amount of interest accrued each day that you do not pay your friend back.
  • If you need to further calculate the total due after 1 day, you would add the amount you borrowed to the amount of the interest times the number of days. So $15 + ($0.45 x 1 day) = $15.45.

Step 4 Bonus Example 1:

  • We can reword this problem as “What is 80% of 35?”
  • Plug the values into the formula P/100 = Part/Whole
  • 80/100 = X/35
  • 35 x 0.8 = X
  • The pitcher won 28 games.

Step 5 Bonus Example 2:

  • We can reword this problem as “What is 93% of 8.15?”
  • 93/100 = X/8.15
  • 0.93 = X/8.15
  • 0.93 x 8.15 = X
  • There are 7.58 ounces of silver.

P Percent of What Number Is Y?

Step 1 Use this method to solve for a missing “whole” when you’re given a percentage and a “part.”

  • Part/Percent (in decimal form) = Whole
  • Keep reading for a full walk-through if you’re not sure how to get there.

Step 2 Convert the percentage into a decimal.

  • 72/100 = 1,380 online sales/Y total sales
  • 72/100 = 1,380/Y
  • 0.72 = 1,380/Y
  • 0.72 x Y = 1,380
  • 1,380/0.72 = Y
  • Y = 1916.66
  • Acme Computers made 1917 total sales this year.
  • 39/100 = 89/Y
  • 0.39 = 89/Y
  • 0.39 x Y = 89
  • 89/0.39 = Y

Calculating Percent Increase

Step 1 Subtract...

  • New Amount - Original Amount = Difference
  • $15.75 - $13.99 = $1.76
  • (Difference / Original Amount) x 100% = Percent Increase
  • ($1.76 / $13.99) x 100% = 12.5%
  • The price of the game went up by 12.5%.

Step 5 Bonus Example 2:

  • $55 - $22 = $33
  • ($33 / $55) x 100% = 60%
  • The company has a 60% markup on sweaters.

Calculating Percent Decrease

Step 1 Subtract the new amount from the original, bigger amount.

  • Original Amount - New Amount = Difference
  • 42 - 39 = 3
  • (3 / 42) x 100% = 7%
  • Jane’s hours decreased by 7%.

Step 5 Bonus Example 2:

  • 563 - 542 = 21
  • (21 / 563) x 100% = 3.7%
  • Company A decreased their number of employees by 3.7%.

Percentage in Real Life

Step 1 Calculate a restaurant...

  • Example: If your bill is $54, a 10% tip would be $5.4.
  • Example: For a $54 bill, 10% is $5.4. Half of $5.4 is $2.7. Finally, $5.4 + $2.7 = $8.1.
  • Example: For a $54 bill, double that is $108. If you move the decimal one place to the left, you'll get $10.80.

Step 2 Calculate your savings...

  • Move the decimal two places to the left . In this example, 70%/100% = 70/100 = 7/10 = 0.7. [30] X Research source
  • Multiply the original price by the new decimal. If the shirt you want is $20, multiply $20 by 0.7. This comes to $14, meaning the shirt is now on sale for $14. [31] X Research source
  • Calculate your savings. Simply subtract the sale price from the original price ($20 - $14 = $6 saved)!

Step 3 Calculate the total...

  • Convert 9% to a decimal: 0.09
  • Add the decimal to 1: 0.09 + 1 = 1.09
  • Multiple that value by the original price: $15 x 1.09 = $16.35
  • Mark will pay $16.35 at checkout.

Math Homework Helper: Percentages and Finding Percents

  •  / 
  • Pre-Algebra

Percentages are used in lots of areas, including statistics, science and finance. In politics, percentages are even used to decide who wins elections. Read this article to learn what a percentage is, and how to calculate one!

Homework Help for Percentages

A percentage represents a fraction with 100 as the denominator. Percentages are written using the percent sign (%). For instance, the fraction 50/100 is written as 50%, and the fraction 8/100 is written as 8%. Here are a few more examples:

  • 15/100 = 15%
  • 75/100 = 75%
  • 110/100 = 110%

Writing Fractions as Percentages

Most of the time, the fractions that we want to turn into percentages don't have 100 as the denominator. For example, if you got 17 questions right on a test with 20 questions, you might want to figure out what percentage 17/20 is equal to. To write fractions as percentages, we have to find an equivalent fraction with a denominator of 100. The fraction 17/20 is equal to 85/100, which is equal to 85%. This means that you got 85% of your test questions correct. Here are some other examples:

  • 2/5 = 40/100 = 40%
  • 1/25 = 4/100 = 4%
  • 18/50 = 36/100 = 36%

Sometimes, when you try to turn a fraction into a percentage, you'll find that it doesn't have an equivalent fraction with a denominator of 100. The fractions 5/24 and 7/8 are examples of this. Here's how you handle this situation:

  • Change the fraction to a decimal by dividing the numerator by the denominator. You can do this by hand or with a calculator. For instance, 7/8 = 0.875.
  • Multiply the resulting decimal by 100. This will tell you what percentage the original fraction is equal to. For example, 0.875 x 100 = 87.5, so 7/8 = 87.5%.

Finding the Percentage of a Quantity

Now that you can turn fractions into percentages, it's time to work backwards. Often, you'll need to find a certain percentage of something. For example, if you have to pay a 5% tax on your grocery bill, or you earn a 10% commission for every candy bar you sell, you'll need to calculate the amount of money those percentages represent.

Calculating Taxes and Tips

One way to do this is to change the percentage into a fraction out of 100, and then multiply it by the amount you're finding the percentage of. For instance, if your grocery bill is $50.00, you can calculate 5% of it by multiplying 50/1 x 5/100. This equals 250/100, which simplifies to 5/2. To get the final amount of tax in dollars, convert 5/2 to a decimal by dividing the numerator by the denominator. Since 5 ÷ 2 = 2.5, the tax on your grocery bill is $2.50. You would use the same steps to figure out the amount of a tip.

Tip : Read percentage problems carefully. In this problem, we were finding the amount of the tax, which was $2.50. Some problems will ask you to find the amount of the total bill with tax, so you would add $2.50 to $50.00 to get $52.50 as your answer.

Calculating Commissions

Let's try another example: Sandra earns a 10% commission for each candy bar she sells, and each candy bar costs $3.00. If she sells 30 candy bars, how much commission will she earn?

The first step is to determine the total value of all of the candy bars sold by multiplying $3.00 by 30. Since $3.00 x 30 = $90.00, Sandra's commission will be equal to 10% of that amount. To calculate the commission, we have to write 10% as the fraction 10/100, and multiply it by $90.00 (10/100 x 90/1). The result is the fraction 900/100, which can be simplified to 9/1. Since 9 ÷ 1 = 9, Sandra's commission will be $9.00.

Tip : If you have a calculator handy, you can change the percentage into a decimal, and multiply the total amount by the decimal to get your answer. For example, 10/100 = 0.1, and $90.00 x 0.1 = $9.00.

How to Practice Percentages

There are tons of opportunities to practice percentage problems in daily life. You can ask your parents to let you calculate the server's tip when you go to a restaurant, or you can calculate the sales tax when you go shopping. You can also survey your friends about their likes and dislikes, and report the results using percentages.

PERCENTAGES

This section will explain how to apply algebra to percentage problems.

In algebra problems, percentages are usually written as decimals.

Example 1. Ethan got 80% of the questions correct on a test, and there were 55 questions. How many did he get right?

The number of questions correct is indicated by:

percentage homework

Ethan got 44 questions correct.

Explanation: % means "per one hundred". So 80% means 80/100 = 0.80.

Example 2. A math teacher, Dr. Pi, computes a student’s grade for the course as follows:

percentage homework

a. Compute Darrel's grade for the course if he has a 91 on the homework, 84 for his test average, and a 98 on the final exam.

percentage homework

Darrel’s grade for the course is an 89.6, or a B+.

b. Suppose Selena has an 89 homework average and a 97 test average. What does Selena have to get on the final exam to get a 90 for the course?

The difference between Part a and Part b is that in Part b we don’t know Selena’s grade on the final exam.

So instead of multiplying 30% times a number, multiply 30% times E. E is the variable that represents what Selena has to get on the final exam to get a 90 for the course.

percentage homework

Because Selena studied all semester, she only has to get a 79 on the final to get a 90 for the course.

Example 3. Sink Hardware store is having a 15% off sale. The sale price of a toilet is $97; find the retail price of the toilet.

a. Complete the table to find an equation relating the sale price to the retail price (the price before the sale).

Vocabulary: Retail price is the original price to the consumer or the price before the sale. Discount is how much the consumer saves, usually a percentage of the retail price. Sale Price is the retail price minus the discount.

percentage homework

b. Simplify the equation.

percentage homework

Explanation: The coefficient of R is one, so the arithmetic for combining like terms is 1 - 0.15 = .85. In other words, the sale price is 85% of the retail price.

c. Solve the equation when the sale price is $97.

percentage homework

The retail price for the toilet was $114.12. (Note: the answer was rounded to the nearest cent.)

The following diagram is meant as a visualization of problem 3.

percentage homework

The large rectangle represents the retail price. The retail price has two components, the sale price and the discount. So Retail Price = Sale Price + Discount If Discount is subtracted from both sides of the equation, a formula for Sale Price is found. Sale Price = Retail Price - Discount

Percentages play an integral role in our everyday lives, including computing discounts, calculating mortgages, savings, investments, and estimating final grades. When working with percentages, remember to write them as decimals, to create tables to derive equations, and to follow the proper procedures to solve equations.

Study Tip: Remember to use descriptive letters to describe the variables.

Percents and Rates

New york state common core math module 1, grade 6, lesson 24.

• Students understand that percents are related to part-to-whole ratios and rates where the whole is 100. • Students model percents and write a percent as a fraction over 100 or a decimal to the hundredths place.

• Percent means out of 100. Therefore, percents are fractions with a denominator of 100. We can create models of percents. One example would be to shade a 10 x 10 grid. Each square in a 10 x 10 grid represents 1% or 0.01.

Percentage Calculator

Please provide any two values below and click the "Calculate" button to get the third value.

Percentage Calculator in Common Phrases

Percentage difference calculator, percentage change calculator, what is a percentage.

0.5 × 100 = 50

In other words, the ratio of 25 males to students in the classroom is equivalent to 50% of students in the classroom being male.

Percentage formula

Although the percentage formula can be written in different forms, it is essentially an algebraic equation involving three values.

P × V 1 = V 2

If solving manually, the formula requires the percentage in decimal form, so the solution for P needs to be multiplied by 100 in order to convert it to a percent. This is essentially what the calculator above does, except that it accepts inputs in percent rather than decimal form.

Percentage difference formula

The percentage difference between two values is calculated by dividing the absolute value of the difference between two numbers by the average of those two numbers. Multiplying the result by 100 will yield the solution in percent, rather than decimal form. Refer to the equation below for clarification.

11 Surprising Homework Statistics, Facts & Data

homework pros and cons

The age-old question of whether homework is good or bad for students is unanswerable because there are so many “ it depends ” factors.

For example, it depends on the age of the child, the type of homework being assigned, and even the child’s needs.

There are also many conflicting reports on whether homework is good or bad. This is a topic that largely relies on data interpretation for the researcher to come to their conclusions.

To cut through some of the fog, below I’ve outlined some great homework statistics that can help us understand the effects of homework on children.

Homework Statistics List

1. 45% of parents think homework is too easy for their children.

A study by the Center for American Progress found that parents are almost twice as likely to believe their children’s homework is too easy than to disagree with that statement.

Here are the figures for math homework:

  • 46% of parents think their child’s math homework is too easy.
  • 25% of parents think their child’s math homework is not too easy.
  • 29% of parents offered no opinion.

Here are the figures for language arts homework:

  • 44% of parents think their child’s language arts homework is too easy.
  • 28% of parents think their child’s language arts homework is not too easy.
  • 28% of parents offered no opinion.

These findings are based on online surveys of 372 parents of school-aged children conducted in 2018.

2. 93% of Fourth Grade Children Worldwide are Assigned Homework

The prestigious worldwide math assessment Trends in International Maths and Science Study (TIMSS) took a survey of worldwide homework trends in 2007. Their study concluded that 93% of fourth-grade children are regularly assigned homework, while just 7% never or rarely have homework assigned.

3. 17% of Teens Regularly Miss Homework due to Lack of High-Speed Internet Access

A 2018 Pew Research poll of 743 US teens found that 17%, or almost 2 in every 5 students, regularly struggled to complete homework because they didn’t have reliable access to the internet.

This figure rose to 25% of Black American teens and 24% of teens whose families have an income of less than $30,000 per year.

4. Parents Spend 6.7 Hours Per Week on their Children’s Homework

A 2018 study of 27,500 parents around the world found that the average amount of time parents spend on homework with their child is 6.7 hours per week. Furthermore, 25% of parents spend more than 7 hours per week on their child’s homework.

American parents spend slightly below average at 6.2 hours per week, while Indian parents spend 12 hours per week and Japanese parents spend 2.6 hours per week.

5. Students in High-Performing High Schools Spend on Average 3.1 Hours per night Doing Homework

A study by Galloway, Conner & Pope (2013) conducted a sample of 4,317 students from 10 high-performing high schools in upper-middle-class California. 

Across these high-performing schools, students self-reported that they did 3.1 hours per night of homework.

Graduates from those schools also ended up going on to college 93% of the time.

6. One to Two Hours is the Optimal Duration for Homework

A 2012 peer-reviewed study in the High School Journal found that students who conducted between one and two hours achieved higher results in tests than any other group.

However, the authors were quick to highlight that this “t is an oversimplification of a much more complex problem.” I’m inclined to agree. The greater variable is likely the quality of the homework than time spent on it.

Nevertheless, one result was unequivocal: that some homework is better than none at all : “students who complete any amount of homework earn higher test scores than their peers who do not complete homework.”

7. 74% of Teens cite Homework as a Source of Stress

A study by the Better Sleep Council found that homework is a source of stress for 74% of students. Only school grades, at 75%, rated higher in the study.

That figure rises for girls, with 80% of girls citing homework as a source of stress.

Similarly, the study by Galloway, Conner & Pope (2013) found that 56% of students cite homework as a “primary stressor” in their lives.

8. US Teens Spend more than 15 Hours per Week on Homework

The same study by the Better Sleep Council also found that US teens spend over 2 hours per school night on homework, and overall this added up to over 15 hours per week.

Surprisingly, 4% of US teens say they do more than 6 hours of homework per night. That’s almost as much homework as there are hours in the school day.

The only activity that teens self-reported as doing more than homework was engaging in electronics, which included using phones, playing video games, and watching TV.

9. The 10-Minute Rule

The National Education Association (USA) endorses the concept of doing 10 minutes of homework per night per grade.

For example, if you are in 3rd grade, you should do 30 minutes of homework per night. If you are in 4th grade, you should do 40 minutes of homework per night.

However, this ‘rule’ appears not to be based in sound research. Nevertheless, it is true that homework benefits (no matter the quality of the homework) will likely wane after 2 hours (120 minutes) per night, which would be the NEA guidelines’ peak in grade 12.

10. 21.9% of Parents are Too Busy for their Children’s Homework

An online poll of nearly 300 parents found that 21.9% are too busy to review their children’s homework. On top of this, 31.6% of parents do not look at their children’s homework because their children do not want their help. For these parents, their children’s unwillingness to accept their support is a key source of frustration.

11. 46.5% of Parents find Homework too Hard

The same online poll of parents of children from grades 1 to 12 also found that many parents struggle to help their children with homework because parents find it confusing themselves. Unfortunately, the study did not ask the age of the students so more data is required here to get a full picture of the issue.

Interpreting the Data

Unfortunately, homework is one of those topics that can be interpreted by different people pursuing differing agendas. All studies of homework have a wide range of variables, such as:

  • What age were the children in the study?
  • What was the homework they were assigned?
  • What tools were available to them?
  • What were the cultural attitudes to homework and how did they impact the study?
  • Is the study replicable?

The more questions we ask about the data, the more we realize that it’s hard to come to firm conclusions about the pros and cons of homework .

Furthermore, questions about the opportunity cost of homework remain. Even if homework is good for children’s test scores, is it worthwhile if the children consequently do less exercise or experience more stress?

Thus, this ends up becoming a largely qualitative exercise. If parents and teachers zoom in on an individual child’s needs, they’ll be able to more effectively understand how much homework a child needs as well as the type of homework they should be assigned.

Related: Funny Homework Excuses

The debate over whether homework should be banned will not be resolved with these homework statistics. But, these facts and figures can help you to pursue a position in a school debate on the topic – and with that, I hope your debate goes well and you develop some great debating skills!

Grade Calculator

Our Grade Calculator can help you determine what you need to get on your final exam to achieve the final grade you would like for a given course.

Do you know your Current Grade?

Fill in your assignment grades on the right to automatically calculate your Current Grade

Grade Needed on Final Exam

percentage homework

Please make sure all text fields are filled out.

Minimum Attainable Course Grade: 0%

Maximum Attainable Course Grade: 100%

Enter your assignment scores here to automatically calculate your current grade (e.g. midterms, homework, tests, labs, etc.)

Important Notes

You can use our grade calculator to calculate the final exam grade you will need to achieve the overall course grade you desire. Our calculator requires you to enter the current percentage grade you have currently obtained for that course together with the weight of the final exam as a percentage value. However, if you do not know what your current grade is, for the question "Do you know your Current Grade?" select the answer "no." Enter the grades you have received for all of your assignments, homework, test, labs, and anything else that contributes to your final grade, as well as the weight of each grade. Our grade calculator will automatically calculate not only your current grade but the grade you need to achieve on your final exam to achieve the overall course grade you desire. In addition, both the minimum and maximum course overall grades will be provided.

Once you have entered the information required, the system will generate both a table and a chart that show the different final exam grades you may obtain as well as the overall course grades that go with them.

Inputting Data in our Grade Calculator

When entering your current grade and the weight of your final exam, our calculator will assume that your current grade has been based on the weight of the course prior to your final exam and calculates it as the input weight subtracted from 100%. If your current grade hasn't taken your coursework into account, the generated results will not be accurate.

Similar to the above, if you don't know what your current grade is and you enter both the coursework grades and the associated weights into the calculator, the calculator will automatically calculate your current grade and the weight of the final exam. In this situation, the weight of your final exam is calculated by taking the sum of the weight of your course work subtracted from 100%. With that in mind, if you enter too many or not enough assignments, the weight of the final exam that is calculated will most likely not match the actual weight of the final exam in your chosen course.
