Question

Виконати дії 2 2/5:(1 11/5-3 2/5)×(-5/6)

Answer 1

$2 \frac{2}{5} \div (1 \frac{11}{5} - 3 \frac{2}{5} ) \times ( - \frac{5}{6} ) = 2 \frac{2}{5} \div (3 \frac{1}{5} - 3 \frac{2}{5} ) \times ( - \frac{5}{6}) = 2 \frac{2}{5} \div ( - \frac{1}{5} ) \times ( - \frac{5}{6} ) = \frac{12 \times 5 \times 5}{5 \times 1 \times 6} = \frac{2 \times 1 \times 5}{1 \times 1 \times 1 } = 2 \times 5 = 10$
