Answer 1

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