Answer 2

Step-by-step explanation:

$\frac{1}{2} + ( - \frac{1}{3} + \frac{2}{3} ) \\ = \frac{1}{2} + ( \frac{ - 1 + 2}{3} ) \\ = \frac{1}{2} + \frac{1}{3} \\ = \frac{3 + 2}{6} \\ = \frac{5}{6}$

$( \frac{1}{2} + - \frac{1}{3}) + \frac{2}{3} \\ = (\frac{3 - 2}{6}) + \frac{ 2}{3} \\ = \frac{1}{6} + \frac{2}{3} \\ = \frac{1+ 4}{6} \\ = \frac{5}{6}$
