60. Найдите произведение: 1) \(5 \frac{3}{26}\); 3) \(\frac{9}{28} \cdot 56\); 5) \(5 \frac{1}{7} \cdot 1 \frac{8}{27}\); 2) \(\frac{9}{8}\); 4) \(6 \frac{3}{4}\); 6) \(1 \frac{9}{8} \cdot 1 \frac{1}{2} \cdot \frac{2}{3}\).

Найдем произведение:

1. \(5 \frac{3}{26} = \frac{5 \cdot 26 + 3}{26} = \frac{130 + 3}{26} = \frac{133}{26}\)

   Ответ: \(\frac{133}{26}\)

2. \(\frac{9}{8}\)

   Ответ: \(\frac{9}{8}\)

3. \(\frac{9}{28} \cdot 56 = \frac{9 \cdot 56}{28} = \frac{9 \cdot 2}{1} = 18\)

   Ответ: 18

4. \(6 \frac{3}{4} = \frac{6 \cdot 4 + 3}{4} = \frac{24 + 3}{4} = \frac{27}{4}\)

   Ответ: \(\frac{27}{4}\)

5. \(5 \frac{1}{7} \cdot 1 \frac{8}{27} = \frac{5 \cdot 7 + 1}{7} \cdot \frac{1 \cdot 27 + 8}{27} = \frac{36}{7} \cdot \frac{35}{27} = \frac{36 \cdot 35}{7 \cdot 27} = \frac{4 \cdot 5}{1 \cdot 3} = \frac{20}{3} = 6 \frac{2}{3}\)

   Ответ: \(6 \frac{2}{3}\)

6. \(1 \frac{9}{8} \cdot 1 \frac{1}{2} \cdot \frac{2}{3} = \frac{1 \cdot 8 + 9}{8} \cdot \frac{1 \cdot 2 + 1}{2} \cdot \frac{2}{3} = \frac{17}{8} \cdot \frac{3}{2} \cdot \frac{2}{3} = \frac{17}{8} \cdot 1 \cdot \frac{1}{1} = \frac{17}{8} = 2 \frac{1}{8}\)

   Ответ: \(2 \frac{1}{8}\)

Ответ: 1) \(\frac{133}{26}\); 2) \(\frac{9}{8}\); 3) 18; 4) \(\frac{27}{4}\); 5) \(6 \frac{2}{3}\); 6) \(2 \frac{1}{8}\).
