Answer

0

Work Step by Step

The additive inverse property holds that $a+(-a)=0$, for some real number $a$. In other words, the property tells us that the sum of a real number $a$ and its negative is equal to 0. In this example, we can set $\frac{2}{3}+(-\frac{2}{3})=a+(-a)$, where $a=\frac{2}{3}$. Therefore, the other side of this equation is 0.
