Answer 1

Всё решила, если не сложно оцените

Answer 2

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

$b) \frac{1}{4} \div \frac{1}{2} = \frac{1}{4} \times 2 = \frac{2}{4} = 0.5$

$c) \frac{2}{5} \div \frac{2}{3} = \frac{2}{5} \times \frac{3}{2} = \frac{3}{5} = 0.6$

$d) \frac{3}{4} \div \frac{1}{2} = \frac{3}{4} \times 2 = \frac{6}{4} = 1.5$

$f) \frac{5}{6} \div \frac{7}{12} = \frac{5}{6} \times \frac{12}{7} = 5 \times \frac{2}{7} = \frac{10}{7} = 1 \frac{3}{7}$
