\(\frac{14}{27} \cdot \frac{3}{7} = \frac{14 \cdot 3}{27 \cdot 7} = \frac{2 \cdot 1}{9 \cdot 1} = \frac{2}{9}\)
Ответ: \(\frac{2}{9}\)
\(\frac{8}{9} \cdot \frac{1}{8} = \frac{8 \cdot 1}{9 \cdot 8} = \frac{1 \cdot 1}{9 \cdot 1} = \frac{1}{9}\)
Ответ: \(\frac{1}{9}\)
\(4 \frac{3}{8} = \frac{4 \cdot 8 + 3}{8} = \frac{32 + 3}{8} = \frac{35}{8} = 4 \frac{3}{8}\)
Ответ: \(4 \frac{3}{8}\)
\(\frac{7}{8} \cdot 4 = \frac{7 \cdot 4}{8} = \frac{7 \cdot 1}{2} = \frac{7}{2} = 3 \frac{1}{2}\)
Ответ: \(3 \frac{1}{2}\)
\(\frac{5}{6} \cdot \frac{5}{9} = \frac{5 \cdot 5}{6 \cdot 9} = \frac{25}{54}\)
Ответ: \(\frac{25}{54}\)
\(6 \cdot 4 \frac{1}{3} = 6 \cdot \frac{4 \cdot 3 + 1}{3} = 6 \cdot \frac{12 + 1}{3} = 6 \cdot \frac{13}{3} = \frac{6 \cdot 13}{3} = \frac{2 \cdot 13}{1} = 26\)
Ответ: 26
\(7 \frac{1}{2} \cdot 1 \frac{5}{9} = \frac{7 \cdot 2 + 1}{2} \cdot \frac{1 \cdot 9 + 5}{9} = \frac{14 + 1}{2} \cdot \frac{9 + 5}{9} = \frac{15}{2} \cdot \frac{14}{9} = \frac{15 \cdot 14}{2 \cdot 9} = \frac{5 \cdot 7}{1 \cdot 3} = \frac{35}{3} = 11 \frac{2}{3}\)
Ответ: \(11 \frac{2}{3}\)
