Answer 1

$( frac{21}{22} - frac{5}{11} ) - ( frac{22}{39} - frac{3}{13} ) = ?$

1)

$frac{21}{22} - frac{5}{11}^{2} = frac{21}{22} - frac{10}{22} = frac{11}{22}^{11} = frac{1}{2}$

2)

$frac{22}{39} - frac{3}{13}^{3} = frac{22}{39} - frac{9}{39} = frac{13}{39} ^{13} = frac{1}{3}$

3)

$frac{1}{2}^{3} - frac{1}{3}^{2} = frac{3}{6} - frac{2}{6} = frac{1}{6}$
