Question

What will be the additive inverse of the rational number $\frac{a}{b}$?

• A. $\frac{b}{a}$
• B. $-\frac{b}{a}$
• C. $\frac{a}{b}$
• D. $-\frac{a}{b}$

Answer 1

The correct option is D $-\frac{a}{b}$

The additive inverse of the rational number $\frac{a}{b}$ is $-\frac{a}{b}$.

In general, the sum of any rational number $\frac{a}{b}$, and its additive inverse is 0.

$\frac{a}{b}+(-\frac{a}{b})=0$
