Question

Express $\frac{27}{-45}$as a rational number with a denominator $5$

Answer 1

Given a rational number $\frac{27}{-45}$

To obtain a rational number with a denominator $5$ we have to divide the denominator of the given rational number by$-9$

If we divide the denominator by$-9$ then we have to divide the numerator by$-9$ also so that the value remains constant

Thus,

$\frac{27}{-45}=\frac{27÷(-9)}{-45÷(-9)}=\frac{-3}{5}$

Hence, the required rational number is $\frac{-3}{5}$
