Fractions and percentages
Connect 1/2, 1/4, 3/4 and tenths to percentage ideas.
Quick answer
Fractions and percentages are different ways to show parts of a whole. 1/2 is the same as 50%, 1/4 is 25%, 3/4 is 75%, and 1/10 is 10%. You can think of percentages as parts out of 100.Learning outcome
By the end of this page, you will understand how to connect simple fractions like 1/2, 1/4, 3/4 and 1/10 to their percentage equivalents. You will be able to see that fractions and percentages are just different ways to show the same amount. Success signs:- You can match a fraction to its percentage (like 1/2 = 50%)
- You can share a group of objects into equal parts and show what percentage each part is
- You can explain why 1/4 of something is the same as 25%
- You can solve simple problems using both fractions and percentages
Why this matters
Understanding fractions and percentages helps you in many real-life situations. When you share a pizza, you might say "I ate 1/4 of it." When you see a sale at the shop, you might hear "25% off everything." When you play board games, you might need to count how many of your pieces are on certain spaces. Knowing how fractions and percentages work helps you make better decisions and solve problems more easily.How it works
Fractions show parts of a whole. For example, if you have a pizza cut into 4 equal pieces and you eat 1 piece, you have eaten 1/4 of the pizza. Percentages are a way of showing parts out of 100. So, 1/4 of a pizza is the same as 25% of the pizza. To connect fractions to percentages, you can think of it like this:- 1 whole = 100%
- 1/2 = 50% (because half of 100 is 50)
- 1/4 = 25% (because a quarter of 100 is 25)
- 3/4 = 75% (because three quarters of 100 is 75)
- 1/10 = 10% (because one tenth of 100 is 10)
Examples you can see
Let’s imagine you have a box of 100 chocolates. If you take 10 chocolates, you have taken 10 out of 100 chocolates. This is 10/100, which is the same as 10%. Now, if you take 25 chocolates, that is 25 out of 100 chocolates. That is 25/100, which is 25%. If you take 50 chocolates, that is 50 out of 100 chocolates. That is 50/100, which is 50%. Try this with your hands: Take 10 coins and put them in a pile. Now take 1 coin out. What fraction of the coins did you take? (1/10) What percentage is that? (10%) Let’s look at a few more examples using shapes.| Fraction | How to think about it | Percentage |
|---|---|---|
| 1/2 | Half of the shape | 50% |
| 1/4 | Quarter of the shape | 25% |
| 3/4 | Three quarters of the shape | 75% |
| 1/10 | One tenth of the shape | 10% |
Try it as a mini adventure
Adventure: The Percentage Pizza Party! You are planning a pizza party for your class. There are 20 children in your class. You want to make sure everyone gets a fair share. 1st time: You decide to make 4 pizzas. Each pizza is cut into 4 equal slices. How many slices does each child get? (20 ÷ 4 = 5 slices each) 2nd time: You notice that 1/4 of the children want to eat only 1 slice. How many children is that? (20 × 1/4 = 5 children) 3rd time: You want to make sure 1/2 of the children get 2 slices. How many children is that? (20 × 1/2 = 10 children) 4th time: You want to make sure 1/10 of the children get 3 slices. How many children is that? (20 × 1/10 = 2 children) Now, let’s turn these fractions into percentages:- 1/4 = 25% of the class
- 1/2 = 50% of the class
- 1/10 = 10% of the class
Common mistakes
- Mistake: Thinking 1/4 = 40% or 1/2 = 60%.
Why it happens: Confusing the numbers in the fraction with the percentage.
Fix: Remember that 1/4 means 1 part out of 4, which is 25% because 100 ÷ 4 = 25. - Mistake: Saying 3/4 = 30%.
Why it happens: Not knowing that 3/4 means 3 parts out of 4, which is 75%.
Fix: Think of 3/4 as 3 quarters of 100. 3 × 25 = 75%. - Mistake: Mixing up 1/10 and 1/2.
Why it happens: Not understanding that 1/10 is much smaller than 1/2.
Fix: Use a visual like a pie chart or a number line to compare the sizes.
Parent and carer guide
As a parent or carer, you can help your child understand fractions and percentages by:- Using real-life examples like sharing food, dividing a cake, or counting coins
- Playing games that involve fractions, such as matching fraction cards to percentage cards
- Using everyday language: “If you eat 1/4 of your sandwich, that’s 25% of it”
- Encouraging your child to draw pictures or use objects to show fractions
- Reinforcing that fractions and percentages are just different ways of showing the same amount
- Ask your child to show you how 1/2 looks compared to 1/4 using a piece of paper
- Use a 100-square grid to help them see 10% as 10 squares out of 100
- Play a game: “What’s the percentage?” with everyday objects
- Use cooking to show how 1/4 cup of flour is the same as 25% of a cup
- Point out percentages in real life: “This sale is 25% off!”

FAQ
What is the difference between a fraction and a percentage?
A fraction shows a part of a whole using two numbers (like 1/4), while a percentage shows a part out of 100 (like 25%).
Why do we need to know about percentages?
Percentages help us compare things easily, like how much money you save in a sale, or how many people like a certain game.
How can I help my child learn fractions and percentages?
You can use everyday examples like sharing food, looking at sale prices, or drawing shapes to show parts.
Can all fractions be turned into percentages?
Yes! Any fraction can be turned into a percentage by thinking of it as parts out of 100.
What if my child is still confused about fractions?
Use hands-on materials like counters, blocks, or drawings. Start with simple examples like 1/2 and 1/4, and build up slowly.
