Question

5 5/7-2/5×(5 1/4 ÷ 1 1/6) помогите

Answer 1

$5 \frac{5}{7} - \frac{2}{5} \times (5 \frac{1}{4} \div 1 \frac{1}{6}) = \frac{137}{35} \\ 1) \frac{21}{4} \div \frac{7}{6} = \frac{21}{4} \times \frac{6}{7} = \frac{9}{2} \\ 2) \frac{2}{5} \times \frac{9}{2} = \frac{9}{5} \\ 3) \frac{40}{7} - \frac{9}{5} = \frac{200 - 63}{35} = \frac{137}{35}$
