Find the missing number in the box in the proportions:
`square/18 = 2/9`
उत्तर
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`.
∴ `4/18 = 2/9`
