Question
Find the missing number in the box in the proportions:
`8/square = 3.2/4`
Solution
In order to get the missing number, we consider the fact that 3.2 × 2.5 = 8, i.e., when we multiply 3.2 by 2.5 we get 8. This indicates that to get the missing number, 4 must also be multiplied by 2.5.
When we multiply, we have, 4 × 2.5 = 10
Hence, the ratio is `8/10`.
∴ `8/10 = 3.2/4`
