$\bf\blue{AnsweR:-}$

GiveN:-

The product of two rational numbers = 15

One of the number = -10

To FinD:-

The other rational number.

SolutioN:-

The product of two rational numbers are given as 15.

As we know , one of the number is -10.

Now, we need to find the other number.

Let, the other rational number be x.

Then,

$\purple{:\implies\bf{x\times-10=15}}$

$\purple{:\implies\bf{x=\dfrac{15}{-10}}}$

$\purple{:\implies\bf{x=\dfrac{-15}{10}}}$

On reducing,

$\purple{:\implies\bf{x=\dfrac{-3}{2}}}$
