A group of 36 students went for a picnic. If 6 students can play with 3 balls. How many balls are required for the group of 36 students?
[1 MARK]

Answer 1

For 6 students we need 3 balls.

$\Rightarrow$ For 1 student, we need $\frac{3}{6}=\frac{1}{2}$ balls.

Therefore, 36 students would need:

$36\times \frac{1}{2}=$ 18 balls.
