Answer 1

Ответ:

$\frac{22}{35} \times m = \frac{2}{7} \\ m = \frac{2}{7} \div \frac{22}{35} = \frac{2}{7} \times \frac{35}{22} \\ m = \frac{5}{11}$

$\frac{8}{15} \times m = \frac{2}{5} \\ m = \frac{2}{5} \div \frac{8}{15} = \frac{2}{5} \times \frac{15}{8} \\ m = \frac{3}{4}$

$m \times \frac{20}{91} = \frac{4}{7} \\ m = \frac{4}{7} \div \frac{20}{91} = \frac{4}{7} \times \frac{91}{20} = \frac{13}{5} = 2 \frac{3}{5}$

$\frac{30}{133} \times m = \frac{6}{7} \\ m = \frac{6}{7} \div \frac{30}{133} = \frac{6}{7} \times \frac{133}{30} = \frac{19}{5} = 3 \frac{4}{5}$
