Express $ \frac{3}{4} $ as a rational number with denominator $ -60 $.

Given:

Given rational number is $\frac{3}{4}$. 

To do: 

We have to express the given rational number as a  rational number with denominator $-60$.

Solution:

To express $\frac{3}{4}$ as a rational number with denominator $-60$, multiply numerator and denominator of $\frac{3}{4}$ by $\frac{-60}{4}=-15$.

Therefore,

$\frac{3}{4}=\frac{3\times-15}{4\times-15}$

$=\frac{-45}{-60}$.

Hence, $\frac{3}{4}=\frac{-45}{-60}$.
