2.303. Выполните умножение: а) \(3\frac{3}{4}\cdot1\frac{3}{5}\); б) \(1\frac{7}{23}\cdot3\frac{5}{6}\); в) \(1\frac{15}{29}\cdot1\frac{9}{20}\); г) \(8\frac{23}{34}\cdot1\frac{17}{59}\); д) \(2\frac{1}{3}\cdot1\frac{4}{5}\cdot1\frac{4}{7}\); е) \(1\frac{4}{9}\cdot3\frac{6}{7}\cdot3\frac{6}{13}\).

1. а) \(3\frac{3}{4}\cdot1\frac{3}{5}=\frac{15}{4}\cdot\frac{8}{5}=6\).
2. б) \(1\frac{7}{23}\cdot3\frac{5}{6}=\frac{30}{23}\cdot\frac{23}{6}=5\).
3. в) \(1\frac{15}{29}\cdot1\frac{9}{20}=\frac{44}{29}\cdot\frac{29}{20}=\frac{11}{5}=2\frac{1}{5}\).
4. г) \(8\frac{23}{34}\cdot1\frac{17}{59}=\frac{295}{34}\cdot\frac{76}{59}=\frac{190}{17}=11\frac{3}{17}\).
5. д) \(2\frac{1}{3}\cdot1\frac{4}{5}\cdot1\frac{4}{7}=\frac{7}{3}\cdot\frac{9}{5}\cdot\frac{11}{7}=\frac{33}{5}=6\frac{3}{5}\).
6. е) \(1\frac{4}{9}\cdot3\frac{6}{7}\cdot3\frac{6}{13}=\frac{13}{9}\cdot\frac{27}{7}\cdot\frac{45}{13}=\frac{135}{7}=19\frac{2}{7}\).

Ответ: а) 6; б) 5; в) \(2\frac{1}{5}\); г) \(11\frac{3}{17}\); д) \(6\frac{3}{5}\); е) \(19\frac{2}{7}\).
