11+ Maths: Converting Decimals to Fractions Practice
21 October 2026
Why decimals to fractions matter
Being able to convert decimals to fractions is a key skill for the 11+ Maths exam. It helps children understand how numbers relate to each other and lays the foundation for more complex topics.
Step 1: Write the decimal as a fraction
Take the decimal number and write it as a fraction with 1 in the denominator. Then, count how many digits are after the decimal point. For example, 0.75 has two decimal places, so write it as 75 over 100.
Step 2: Simplify the fraction
Find the greatest common divisor for the numerator and denominator. In our example, both 75 and 100 can be divided by 25. Divide both numbers by 25 to simplify the fraction.
Worked example
0.75
0.75 = 75/100
75 ÷ 25 = 3 100 ÷ 25 = 4
So, 0.75 = 3/4
Step 3: Check your answer
The simplified fraction should not have any common factors left. This means you have found the simplest form. For 0.75, the answer is 3/4.
Key insight: Converting decimals to fractions helps children recognise number patterns and prepares them for a range of 11+ Maths questions, from arithmetic to problem solving.
