Convert Fractions to Decimals Easily for 11+ Maths
21 October 2026
Why converting fractions to decimals matters
Converting fractions to decimals is a key skill for 11+ maths. Children need to move confidently between these forms to answer questions on number, measures and problem solving.
Step 1: Divide the numerator by the denominator
To convert a fraction to a decimal, divide the top number (numerator) by the bottom number (denominator).
Step 2: Work through the division
Use short division if needed. This helps children see the process clearly, especially with more challenging fractions.
Worked example
Convert 3/4 to a decimal:
3 divided by 4 = 0.75
Step 3: Write the answer as a decimal
Once the division is done, write the answer as a decimal. For 3/4, we write 0.75.
Summary of the process
Converting a fraction to a decimal is simply dividing the numerator by the denominator. The correct answer is 0.75.
Key insight: Practise with different fractions, including those that do not give a whole number answer. Encourage your child to check by multiplying the decimal back by the denominator to see if they get the original numerator.
