Adding Proper Fractions with the Same Denominator: Step-by-Step Example
22 October 2026

When children start learning about fractions, adding them can seem tricky at first. If both fractions have the same denominator, the method is simple and easy to remember.

Example question
What is 2/7 + 3/7?
Step 1: Check the denominators. Both are 7, so they are the same.
Step 2: Add the numerators. 2 + 3 = 5.
Step 3: Keep the denominator the same. It stays as 7.
Key insight: Only add the top numbers. The bottom number does not change.
The answer is 5/7.
Now your child can spot when two fractions have the same denominator and knows exactly how to add them. This type of question often appears in 11+ maths, so practising similar problems will help build confidence.
