Percentage word problems are mathematical exercises or questions that involve the concept of percentages. In these problems, a certain quantity is expressed as a percentage of another quantity, and students are tasked with finding the solution. These types of word problems are common in everyday life and various fields such as finance, economics, science, and business. They often require students to understand how percentages work and how they relate to fractions and decimals.
These problems can vary in complexity, ranging from basic percentage calculations, such as finding a percentage of a quantity, to more advanced scenarios involving discounts, tax, interest rates, and growth or reduction percentages. The goal of percentage word problems is to apply mathematical concepts to real-world situations, improving problem-solving skills and mathematical fluency.
The worksheet presented is a math exercise focused on percentage word problems. It consists of ten questions that involve calculating discounts, test scores, proportions of ingredients, expenditures, and various other scenarios where percentages are used to determine quantities. Each question provides a practical situation where students must apply their understanding of percentages to solve the problem.
This worksheet is designed to teach students how to apply the concept of percentages to real-world problems.

This worksheet is comprised of ten questions, each presenting a unique scenario in which students must calculate the results of percentage increases, decreases, or proportions. The questions cover various situations, such as discounts during a sale, increments in allowance, participation rates in an activity, price adjustments, and changes in performance metrics. Each problem requires the student to apply their understanding of percentages to figure out the numerical outcome based on the information provided.
The worksheet is designed to further develop students’ proficiency with percentages, particularly in understanding how they are used to represent changes and comparisons. It teaches students to perform calculations involving percentage increase and decrease, which are common in financial literacy, statistics, and consumer mathematics. The variety of contexts presented in the problems also serves to show students the wide range of real-life applications for percentage calculations, thereby enhancing their practical mathematical skills.
How to Solve Percentages Word Problems
Solving percentage word problems involves understanding the relationships between parts, whole, and percentages, and applying that knowledge to real-world scenarios. Here is a detailed series of steps to help you solve percentage word problems:
Step 1: Understand the Problem
Carefully read the word problem to understand the context and what is being asked. Pay attention to the given information and what you need to find.
Step 2: Identify the Key Values
Identify the key values in the problem, which typically include:
The “part”: This is the value or quantity that represents the percentage of something.
The “whole”: This is the total amount or quantity from which the percentage is taken.
The “percentage”: This is the percentage that you need to find or work with.
Label these values clearly.
Step 3: Translate the Percentage into Decimal
Convert the given percentage into a decimal by dividing it by 100. This step makes it easier to perform calculations later.
Step 4: Determine the Equation
Use the following formula as the basis for your equation:
Part = (Percentage/100) x Whole
Step 5: Solve the Equation
Plug in the values from the problem into the equation.
Solve for the unknown value (part, whole, or percentage).
Step 6: Check Your Answer
Double-check your solution by re-reading the problem and ensuring that your answer makes sense in the context of the problem.
Example 1: Alice scored 85% on her math test, which had a total of 50 questions. How many questions did she answer correctly?
Step 1: Understand the Problem
Alice’s math test score is given as a percentage, and we need to find the number of questions she answered correctly.
Step 2: Identify the Key Values
Part (questions answered correctly): ?
Whole (total questions): 50
Percentage: 85%
Step 3: Translate the Percentage into Decimal
85% = 0.85 (85 divided by 100)
Step 4: Determine the Equation
Part = (0.85) x 50
Step 5: Solve the Equation
Part = 42.5
Step 6: Check Your Answer
It’s not possible to have half a question, so we round down to the nearest whole number.
Alice answered 42 questions correctly.
Example 2: A pair of shoes originally cost $80, but they are now on sale for 30% off. What is the sale price of the shoes?
Step 1: Understand the Problem
We want to find the sale price of a pair of shoes after a 30% discount is applied.
Step 2: Identify the Key Values
Part (sale price): ?
Whole (original price): $80
Percentage: 30%
Step 3: Translate the Percentage into Decimal
30% = 0.30
Step 4: Determine the Equation
Part = (0.30) x 80
Step 5: Solve the Equation
Part = 0.30 x 80
Part = $24
Step 6: Check Your Answer
The sale price of the shoes is $24 after applying a 30% discount.
