Answer 1

$1 - ( \frac{1}{6} + \frac{1}{5} ) = 1 - \frac{5 + 6}{30} = \frac{30 }{30} - \frac{11}{30} = \frac{19}{30} \\ 1 - ( \frac{1}{8} + \frac{1}{2} ) = 1 - \frac{2 + 8}{16} = 1 - \frac{10}{16} = 1 - \frac{5}{8} = \frac{3}{8} \\ 1 - ( \frac{1}{4} + \frac{1}{5} ) = 1 - \frac{9}{20} = \frac{11}{20} \\ 1 - ( \frac{3}{5} + \frac{1}{10} ) = 1 - \frac{7}{10} = \frac{3}{10}$
