Задание 2. Найдите произведение:

a) \(\frac{6}{17} \cdot 1\frac{8}{9} \cdot \frac{5}{8} = \frac{6}{17} \cdot \frac{17}{9} \cdot \frac{5}{8} = \frac{6 \cdot 17 \cdot 5}{17 \cdot 9 \cdot 8} = \frac{510}{1224} = \frac{5}{12} \cdot \frac{3}{4}= \frac{15}{48}\) б) \(1\frac{7}{8} \cdot 1\frac{1}{15} \cdot 1\frac{7}{16} = \frac{15}{8} \cdot \frac{16}{15} \cdot \frac{23}{16} = \frac{15 \cdot 16 \cdot 23}{8 \cdot 15 \cdot 16} = \frac{5520}{1920} = \frac{23}{8} = 2\frac{7}{8}\) в) \(2\frac{5}{8} \cdot 2 \cdot 2\frac{2}{7} = \frac{21}{8} \cdot 2 \cdot \frac{16}{7} = \frac{21 \cdot 2 \cdot 16}{8 \cdot 1 \cdot 7} = \frac{672}{56} = 12\)
