1. Выполните действия: а) \(\frac{15}{16}\cdot\frac{12}{25}\); б) \(24\cdot\frac{3}{8}\); в) \(\frac{2}{5}:\frac{7}{8}\); г) \(1\frac{1}{3}:\frac{1}{6}\).

1. \(\frac{15}{16}\cdot\frac{12}{25}=\frac{9}{20}\).
2. \(24\cdot\frac{3}{8}=9\).
3. \(\frac{2}{5}:\frac{7}{8}=\frac{2}{5}\cdot\frac{8}{7}=\frac{16}{35}\).
4. \(1\frac{1}{3}:\frac{1}{6}=\frac{4}{3}\cdot6=8\).

Ответ: а) \(\frac{9}{20}\); б) 9; в) \(\frac{16}{35}\); г) 8.
