What fractions, decimals & percentages means

You learn how to move between fractions, decimals and percentages. This helps you compare amounts, check prices and solve simple real-life questions quickly.

What you will practise

  • Change a fraction into a decimal
  • Write a decimal as a fraction in simplest form
  • Convert a fraction or decimal into a percentage
  • Find a percentage of a given amount

Before you start

You should already know basic multiplication, division and place value in decimals. It also helps to understand equivalent fractions and simple times tables.

Not confident yet? Work through Operations with integers first.

Worked example

One question from this skill's own question bank, shown with its full working.

Question

Write 3/4 as a percentage.

  • 25%
  • 34%
  • 75%
  • 80%
Answer: 75%

Working: 3 ÷ 4 = 0.75, and 0.75 × 100 = 75%.

Common mistakes to avoid

  • Forgetting to multiply by 100 when changing a decimal to a percentage.
  • Leaving a fraction unsimplified when the question asks for the simplest form.
  • Using the wrong denominator or place value when turning decimals into fractions.
  • Working out a percentage of a quantity without changing the percent to a decimal first.
