# The product of two rational numbers is −9.

Question:

The product of two rational numbers is −9. If one of the numbers is −12, find the other.

Solution:

Let the number be $\mathrm{x}$.

Now,

$\mathrm{x} \times(-12)=-9$

$\Rightarrow \mathrm{x}=-9 \div(-12)$

$\Rightarrow \mathrm{x}=(-9) \times \frac{1}{-12}$

$\Rightarrow \mathrm{x}=\frac{-9}{-12}$

$\Rightarrow \mathrm{x}=\frac{3}{4}$
