Subtract Fractions with the Same Denominator Using Area Models: Example Question
31 October 2026
Subtracting fractions with the same denominator can feel much simpler when you use an area model. This visual method helps children see exactly what is being taken away, making the process clear and easy to follow.
Worked example
Question: What is 5/8 - 3/8? Use an area model to help you.
Step 1: Draw a rectangle and split it into 8 equal parts. Each part is one eighth.
Step 2: Shade 5 out of the 8 parts. This shows 5/8.
Step 3: Cross out 3 of the shaded parts. This means you are taking away 3/8.
Step 4: Count how many shaded parts are left. There are 2 shaded parts.
Key insight: When the denominators are the same, just subtract the numerators.
So, 5/8 - 3/8 = 2/8.
Now your child can spot that when subtracting fractions with the same denominator, only the top numbers change. They will be ready to try similar questions using area models and build confidence with this key 11+ skill.
