Question
Find xsuch that $\frac{-3}{4}$and $\frac{x}{-36}$ are equivalent rational numbers.

Answer

Since, $\frac{-3}{4}$ and $\frac{x}{-36}$ are equivalent rational numbers.
$\therefore \frac{-3}{4}=\frac{x}{-36} \Rightarrow x=\frac{-36 \times(-3)}{4} \Rightarrow x=-9 \times(-3)=27$
Hence, the value of x is 27.
