A group of 25 Grade 7 learners watched a soccer match. The ratio of the number of boys to the number of girls was 2 ∶ 3. How many boys were there?

Explanation:

boys:girls = 2:3

This means that boys have $\dfrac{2}{5}$ share of the 25 learners in the class whilst the girls had a share of $\dfrac{3}{5}$.

$$\dfrac{2}{5} \times 25 = 10$$

Therefore there were 10 boys.
