(2 times frac{1}{3}) {}^{2} - frac{4}{9}
 frac{2}{3} {}^{2} - frac{4}{9}
 frac{2}{3} times frac{2}{3} = frac{4}{6} = frac{2}{3}
 frac{2}{3} - frac{4}{9} = frac{6}{9} - frac{4}{9} = frac{2}{9}
=========================================
(1 times frac{1}{2} ) {}^{3} + frac{5}{8}
 frac{1}{2} times frac{1}{2} times frac{1}{2} = frac{1}{8}
 frac{1}{8} + frac{5}{8} = frac{6}{8} = frac{3}{4}
=========================================
3 frac{5}{9} +( frac{2}{3}) {}^{2}
 frac{2}{3} times frac{2}{3} = frac{4}{9}
