Answer 1

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