31 October 2026

Unit fractions are a key part of early fractions work. On a number line, they help children see how a whole can be split into equal parts. This example question shows how to spot a unit fraction on a number line, step by step.

Example question
Here is a number line from 0 to 1. It is split into 4 equal parts. There is a mark at the first part after 0. What fraction does the mark show?
Step 1: Count how many equal parts there are from 0 to 1. There are 4 equal parts. The denominator is 4.
Step 2: Count how many parts from 0 to the mark. The mark is at the first part after 0. The numerator is 1.
Step 3: Write the fraction. It is 1/4.
Key insight: A unit fraction always has 1 as the numerator.
Answer: The mark shows 1/4.
