60. Найдите произведение: 1) 7 · 4/37; 2) 7/15 · 3; 3) 8/13 · 26; 4) 3 3/8 · 7/9; 5) 4 4/7 · 2 11/12; 6) 1 2/13 · 1 5/8 · 1 1/7.

1. \(7 \cdot \frac{4}{37}=\frac{28}{37}\).
2. \(\frac{7}{15}\cdot 3=\frac{21}{15}=\frac{7}{5}=2\frac{2}{5}\).
3. \(\frac{8}{13}\cdot 26=8\cdot 2=16\).
4. \(3\frac{3}{8}\cdot\frac{7}{9}=\frac{27}{8}\cdot\frac{7}{9}=\frac{3\cdot 7}{8}=\frac{21}{8}=2\frac{5}{8}\).
5. \(4\frac{4}{7}\cdot 2\frac{11}{12}=\frac{32}{7}\cdot\frac{35}{12}=\frac{40}{3}=13\frac{1}{3}\).
6. \(1\frac{2}{13}\cdot 1\frac{5}{8}\cdot 1\frac{1}{7}=\frac{15}{13}\cdot\frac{13}{8}\cdot\frac{8}{7}=\frac{15}{7}=2\frac{1}{7}\).

Ответ: 1) \(\frac{28}{37}\); 2) \(2\frac{2}{5}\); 3) \(16\); 4) \(2\frac{5}{8}\); 5) \(13\frac{1}{3}\); 6) \(2\frac{1}{7}\).
