2. Вычислите: а) \(4\frac{1}{6}\cdot 3\frac{2}{5}\); б) \(1\frac{8}{12}:1\frac{4}{11}\); в) \(2\frac{8}{9}\cdot1\frac{1}{4}:3\frac{2}{8}\).

а) \(4\frac{1}{6}\cdot3\frac{2}{5}=\frac{25}{6}\cdot\frac{17}{5}=\frac{85}{6}=14\frac{1}{6}\).

б) \(1\frac{8}{12}:1\frac{4}{11}=\frac{5}{3}:\frac{15}{11}=\frac{5}{3}\cdot\frac{11}{15}=\frac{11}{9}=1\frac{2}{9}\).

в) \(2\frac{8}{9}\cdot1\frac{1}{4}:3\frac{2}{8}=\frac{26}{9}\cdot\frac{5}{4}:\frac{13}{4}=\frac{26}{9}\cdot\frac{5}{4}\cdot\frac{4}{13}=\frac{10}{9}=1\frac{1}{9}\).

Ответ: а) \(14\frac{1}{6}\); б) \(1\frac{2}{9}\); в) \(1\frac{1}{9}\).
