Вопрос:

Accepted Answer

\(\frac{5}{7}:\frac{4}{5}=\frac{5}{7}\cdot\frac{5}{4}=\frac{25}{28}\).
\(\frac{6}{35}:\frac{18}{49}=\frac{6}{35}\cdot\frac{49}{18}=\frac{7}{15}\).
\(\frac{27}{28}:\frac{9}{56}=\frac{27}{28}\cdot\frac{56}{9}=6\).
\(\frac{28}{45}:\frac{63}{40}=\frac{28}{45}\cdot\frac{40}{63}=\frac{32}{81}\).
\(6:\frac{2}{7}=6\cdot\frac{7}{2}=21\).
\(\frac{7}{25}:28=\frac{7}{25}\cdot\frac{1}{28}=\frac{1}{100}\).
\(2\frac{2}{3}:2\frac{2}{7}=\frac{8}{3}:\frac{16}{7}=\frac{8}{3}\cdot\frac{7}{16}=\frac{7}{6}=1\frac{1}{6}\).
\(4\frac{4}{9}:\frac{5}{27}=\frac{40}{9}\cdot\frac{27}{5}=24\).
