Answer 1

Пошаговое объяснение:

1)

$\frac{2}{5} \div \frac{2}{25} = \frac{2}{5} \times \frac{25}{2} = 5$

2)

$\frac{2}{3} \div \frac{14}{15} = \frac{2}{3} \times \frac{15}{14} = \frac{5}{7}$

3)

$\frac{3}{28} \div \frac{6}{7} = \frac{3}{28} \times \frac{7}{6} = \frac{1}{8} = 0.125$

4)

$\frac{3}{8} \div \frac{27}{32} = \frac{3}{8} \times \frac{32}{27} = \frac{4}{9}$
