Answer 2

Given,

Condition = a number whose half when multiplied by its one-ninth becomes 648

To find,

The number which will obey the given condition.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

Let, the number = x

Half of the number = x/2

one-ninth of the number = x × 1/9 = x/9

According to the data mentioned in the question,

x/2 × x/9 = 648

x²/18 = 648

x² = 648×18

x² = 11664

x = ±108

(This number(s) satisfy the given conditions.)

Hence, the required number(s) is ±108
