Answer

$-\frac{1}{2}$

Work Step by Step

The additive inverse is the opposite of a number. The sum of a number and its additive inverse is 0. Therefore, the additive inverse of $\frac{1}{2}$ is $-(\frac{1}{2})=-\frac{1}{2}$. We can check to make sure the sum of these two numbers is 0. $-\frac{1}{2}+\frac{1}{2}=\frac{1}{2}-\frac{1}{2}=0$
