Answer 2

Given,

The given number is :

$\frac{ - 8}{15}$

To find,

The number that should be multiplied with the given number to get 8 as the product.

Solution,

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

Let, the number that should be multiplied with the given number = x

(Here, x is an assumed variable for the sake of easier calculations.)

So,

Their product :

$= \frac{ - 8}{15} \times x$

$= \frac{ - 8x}{15}$

According to the data mentioned in the question,

$\frac{ - 8x}{15} = 8$

$- 8x = 15 \times 8$

$- 8x = 120$

$x = (120) \div ( - 8)$

$x = - 15$

(This value of x will be the number which is needed to be multiplied with the given number.)

Hence, we have multiply by (-15)
