Срочно!!! 4 3/7 ÷ 1/7 - 1 5/6 × 12 + (1 1/3)² × (1 1/2) ³= (3/7 - 5/6) × 1 2/13 =

Решите задачу:

$4 \frac{3}{7} \div \frac{1}{7} - 1 \frac{5}{6} \times 12 + (1 \frac{1}{3} ) ^{2} \times {(1 \frac{1}{2} )}^{3} = \frac{31 \times 7}{7} - \frac{11 \times 12}{6} + ( { \frac{4}{3}) }^{2} \times ( \frac{3}{2} ) ^{3} = 31 - 11 \times 2 + \frac{ {4}^{2} \times {3}^{3} }{ {3}^{2} \times {2}^{3} } = 31 - 22 + \frac{16 \times 3}{8} = 9 + 2 \times 3 = 9 + 6 = 15$
$( \frac{3}{7} - \frac{5}{6} ) \times 1 \frac{2}{13} = ( \frac{3}{7} - \frac{5}{6} ) \times \frac{15}{13} = \frac{3 \times 15}{7 \times 13} - \frac{5 \times 15}{6 \times 13} = \frac{45}{91} - \frac{5 \times 5}{2 \times 13} = \frac{45}{91} - \frac{25}{26} = \frac{45 \times 2 - 25 \times 7}{182} = \frac{90 - 175}{182} = - \frac{85}{182}$
