Hello, Year 6! Today, we’re going to explore how to convert fractions into percentages. This is an important skill that can help you understand parts of a whole in different ways. Let’s break it down step by step.

What are Fractions?

A fraction represents a part of a whole. For example, if you have a pizza cut into 4 equal slices and you eat 1 slice, you have eaten $$\frac{1}{4}$$ of the pizza.

What are Percentages?

A percentage is a way of expressing a number as a part of 100. So, if you have 25 out of 100, it’s written as 25%.

How to Convert Fractions to Percentages

To convert a fraction to a percentage, you can follow these steps:

  1. Divide the top number (numerator) by the bottom number (denominator).
  2. Multiply the result by 100.

Example

Let’s convert the fraction $$\frac{3}{4}$$ to a percentage.

  1. Divide: $$3 \div 4 = 0.75$$
  2. Multiply: $$0.75 \times 100 = 75$$

So, $$\frac{3}{4}$$ is equal to 75%.

Key Rules

  • Remember that 100% means the whole.
  • If a fraction equals a half, it will always be 50%.
  • If a fraction has a denominator of 10, you can easily read the percentage. For example, $$\frac{7}{10}$$ is 70%.

Tips and Tricks

  • Use simple fractions: Start with fractions like $$\frac{1}{2}$$, $$\frac{1}{4}$$, and $$\frac{3}{4}$$.
  • Check your work: If you get a percentage, you can double-check by converting it back to a fraction.
  • Use a calculator for larger numbers: This can save time and help you avoid mistakes.
