Question

Помогите решить пример

Answer 1

$frac{( - 20 frac{3}{5} + 21.7) times | - 1 frac{1}{7} | }{(32 frac{8}{5} + ( - 29 frac{3}{5})) div frac{11}{25} } - ( - 17) = 17 frac{121}{875} \ - - - - - - - - \ 1) : : : - 20 frac{3}{5} + 21.7 = - 20 frac{3}{5} + 21 frac{7}{10} = 21 frac{7}{10} - 20 frac{6}{10} = 1 frac{1}{10} \ 2) : : : 1 frac{1}{10} times | - 1 frac{1}{7} | = frac{11}{10} times frac{8}{7} = frac{11 times 4}{5 times 7} = frac{44}{35} = 1 frac{9}{35} \ 3) : : : 32 frac{8}{5} + ( - 29 frac{3}{5} ) = 3 frac{8 - 3}{5} = 3 frac{5}{5} = 4 \ 4) : : : 4 div frac{11}{25} = frac{4 times 25}{11} = frac{100}{11} = 9 frac{1}{11} \ 5) : : : 1 frac{9}{35} div 9 frac{1}{11} = frac{44}{35} div frac{100}{11} = frac{44 times 11}{35 times 100} = frac{11 times 11}{35 times 25} = frac{121}{875} \ 6) : : : frac{121}{875} - ( - 17) = frac{121}{875} + 17 = 17 frac{121}{875}$
