Выполните действия: 1)8: 4/5 2) 1: 7/16

Answer 1

1) $8: \frac{4}{5}$
    $8* \frac{5}{4}$
    $2*5=10$

2) $1: \frac{7}{16}$
    $1* \frac{16}{7}$
    $\frac{16}{7} =2 \frac{2}{7}$

Answer 2

$1)8 \div \frac{4}{5} = \frac{8}{1} \times \frac{5}{4} = \frac{8 \times 5}{1 \times 4} = \frac{2 \times 5}{4} = \frac{10}{4} = 2.5$

$2)1 \div \frac{7}{16} = \frac{1}{1} \times \frac{16}{7} = \frac{1 \times 16}{1 \times 7} = \frac{16}{7} = 2 \frac{2}{7}$
