Деление дробей: 2) \(\frac{6}{35}:\frac{18}{49}\); 3) \(\frac{27}{28}:\frac{9}{56}\); 4) \(\frac{13}{40}:\frac{4}{5}\); 5) \(2\frac{2}{3}:2\frac{2}{7}\); 6) \(4\frac{4}{9}:\frac{5}{27}\).

1. \(\frac{6}{35}:\frac{18}{49}=\frac{6}{35}\cdot\frac{49}{18}=\frac{7}{15}\).
2. \(\frac{27}{28}:\frac{9}{56}=\frac{27}{28}\cdot\frac{56}{9}=6\).
3. \(\frac{13}{40}:\frac{4}{5}=\frac{13}{40}\cdot\frac{5}{4}=\frac{13}{32}\).
4. \(2\frac{2}{3}:2\frac{2}{7}=\frac{8}{3}:\frac{16}{7}=\frac{8}{3}\cdot\frac{7}{16}=\frac{7}{6}=1\frac{1}{6}\).
5. \(4\frac{4}{9}:\frac{5}{27}=\frac{40}{9}\cdot\frac{27}{5}=24\).

Ответ: 2) \(\frac{7}{15}\); 3) 6; 4) \(\frac{13}{32}\); 5) \(1\frac{1}{6}\); 6) 24.
