Question

Find the missing number in the box
in the proportion:

`square/18 = 2/9`

Answer 1

In order to get the missing number, we consider the fact that 9 × 2 = 18, i.e., when we multiply 9 by 2 we get 18. This indicates that to get the missing number, 2 must also be multiplied by 2.

When we multiply, we have, 2 × 2 = 4

Hence, the ratio is `4/18`.

∴ \[\frac{\boxed{4}}{18} = \frac{2}{9}\]
