помогите срочно ​

Answer 1

Пошаговое объяснение:

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

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

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

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