Graph and compare fractions with the same denominator on number lines: Example question
31 October 2026
When children learn about fractions, using a number line helps them see which fraction is bigger or smaller. If the denominators are the same, it's easy to compare their positions by counting along the line.
Example question
Compare 3/8 and 5/8 using a number line.
Step 1: Draw a number line from 0 to 1.
Step 2: Split the line into 8 equal parts. This is because the denominator is 8.
Step 3: Find 3/8. Start at 0 and count 3 parts to the right. Mark this spot as 3/8.
Step 4: Find 5/8. Start at 0 and count 5 parts to the right. Mark this spot as 5/8.
Step 5: Look at both marks. 5/8 is further right than 3/8.
The answer is: 5/8 is greater than 3/8.

Key insight: When two fractions have the same denominator, the one further to the right on the number line is always greater. Your child can now spot which is bigger just by looking at where each fraction sits. Practice questions like this will help them feel confident with comparing fractions using number lines.
