Question

Multiplicative inverse of $\frac{1}{-5}$ is

• A. $\frac{1}{-5}$
• B. $-5$
• C. $\frac{5}{1}$
• D. $Notdefined$

Answer 1

The correct option is B $-5$

As we know that multiplicative inverse of $\frac{a}{b}$ will be $\frac{b}{a}$.

Therefore,

Multiplicative inverse of $\frac{1}{-5}=\frac{-5}{1}=-5$
