20 October 2026
Why converting decimals to fractions matters
Converting decimals to fractions is a key skill for the 11+ Maths exam. It builds confidence with numbers and supports other topics like percentages and ratios.
Step-by-step conversion example
Let's convert 0.75 to a fraction together. Each step is shown clearly so you can practise with your child.
Worked example
Write 0.75 as a fraction with 1 as the denominator:
0.75 = 0.75/1
Multiply both the top and bottom by 100 to remove the decimal:
0.75 × 100 = 75 1 × 100 = 100 So, 0.75/1 = 75/100
Find the highest common factor of 75 and 100, which is 25. Divide both by 25 to simplify:
75 ÷ 25 = 3 100 ÷ 25 = 4 So, 75/100 = 3/4
The correct answer is 3/4.
Key insight:
Understanding how to convert decimals to fractions helps children spot connections between different types of numbers. This makes it easier to tackle a wide range of 11+ questions.
Keep practising together
Regular short practice sessions help children remember the steps and gain confidence. Try different decimals and encourage your child to explain each step out loud.
