Question

Write $\frac{-7}{-3}$ as a rational number with denominator $-15$.

Answer 1

Given rational number: $\frac{-7}{-3}$

We are having $-3$ in the denominator and we have to make it $-15$.

So we just need to divide $-15$ by $-3$ and we get $5$.

Now it is clear that we just need to multiply $5$ in numerator and denominator both.

So,

$\frac{(-7)\times \left(5\right)}{(-3)\times \left(5\right)}=\frac{-35}{-15}$

Snice we cannot disturb the actual value of the rational number so we have to multiply $5$ in numerator and denominator both.

Hence, $\frac{-7}{-3}$ as a rational number with denominator $-15$ is $\frac{-35}{-15}$.
