Answer 1

$\frac{2}{3} \times ( \frac{2}{3} - \frac{1}{2} ) + ({ \frac{1}{2} })^{2} - \frac{4}{5}$

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

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

$\frac{2}{3} \times \frac{1}{6} + \frac{1}{4} - \frac{4}{5}$

$\frac{2}{18} + \frac{1}{4} - \frac{4}{5}$

$\frac{20}{180} + \frac{45}{180} - \frac{144}{180}$

$\frac{65}{180} - \frac{144}{180}$

$- \frac{79}{180}$
