Question

The product of two rational numbers is 15. If one of the numbers is -10, find the other.

Answer 1

Given:

Product of two numbers = 15

And, One number = -10

Let the other rational number is $x$

So, $-10\times x=15$

$\Rightarrow x=\frac{15}{-10}$

$\Rightarrow x=\frac{-3}{2}$

So, the rational number is $\frac{-3}{2}$
