How to convert fractions to decimals for 11+ maths
19 October 2026
Why fractions to decimals matter
Understanding how to convert fractions to decimals is a key skill for the 11+ maths exam. Questions often require children to switch between different forms of numbers, so being confident with these conversions can make a real difference.
Fractions and decimals explained
A fraction like 3/4 shows a part of a whole, while a decimal like 0.75 expresses the same idea in a different way. Both forms are used in the 11+ exam, so it helps to see how they connect.
Step-by-step method
To convert a fraction to a decimal, simply divide the numerator (the top number) by the denominator (the bottom number). For example, to turn 3/4 into a decimal, calculate 3 ÷ 4, which gives 0.75.
Key insight: Every fraction is a division problem. Once you divide the top by the bottom, you have the decimal form.
Common examples
Some fractions and their decimals come up often in 11+ maths:
- 1/2 = 0.5
- 1/4 = 0.25
- 2/5 = 0.4
- 3/8 = 0.375
Practising these helps children spot patterns and work faster.
Tips for practising together
Work through examples on paper or with a calculator. Ask your child to explain their steps out loud. Mix in both simple and trickier fractions to build confidence.
Pitfalls to avoid
Watch out for mistakes like dividing the wrong way round, or forgetting to check if the answer makes sense. If the numerator is smaller than the denominator, the decimal should be less than 1.
