Answer 1

Ответ:

$1) \frac{1}{x} = \frac{5}{8} \\ \times = \frac{1 \times 8}{5} \\ x = \frac{8}{5} = 1 \times \frac{3}{5}$

$2) \frac{1}{y} = \frac{2}{7} \\ y = \frac{7 \times 1}{2} \\ y = \frac{7}{2} = 3 \times \frac{1}{2}$

$3) \frac{1}{z} = \frac{2}{5} \\ z = \frac{5 \times 1}{2} \\ z = \frac{5}{2} = 2 \times \frac{1}{2}$
