Question

Additive inverse of $\frac{5}{2}$ and $\frac{2}{5}$ respectively are

• A. $\frac{2}{5}$ and $\frac{5}{2}$
• B. $-\frac{5}{2}$ and $-\frac{2}{5}$
• C. $\frac{5}{2}$ and $-\frac{2}{5}$
• D. $-\frac{2}{5}$ and $-\frac{5}{2}$

Answer 1

The correct option is B $-\frac{5}{2}$ and $-\frac{2}{5}$

Additive inverse of $\frac{5}{2}$ is $-\frac{5}{2}$, since $\frac{5}{2}+-\frac{5}{2}=0$
Additive inverse of $\frac{2}{5}$ is $-\frac{2}{5}$, since $\frac{2}{5}+-\frac{-2}{5}=0$
