Вычислите: А) \(\frac{1}{2}\cdot1\frac{1}{2}\); Б) \(\frac{1}{3}\cdot4\frac{1}{5}\); В) \(\frac{7}{8}\cdot5\frac{1}{3}\); Г) \(1\frac{1}{2}\cdot\frac{2}{9}\); Д) \(\frac{1}{7}\cdot15\frac{2}{7}\); Е) \(\frac{1}{8}\cdot16\frac{8}{9}\); Ж) \(\frac{3}{7}\cdot2\frac{1}{3}\); З) \(1\frac{1}{7}\cdot3\frac{1}{16}\); И) \(4\frac{1}{2}\cdot2\frac{4}{5}\); К) \(4\frac{1}{2}\cdot\frac{14}{45}\).

1. А) \(\frac{1}{2}\cdot\frac{3}{2}=\frac{3}{4}\).
2. Б) \(\frac{1}{3}\cdot\frac{21}{5}=\frac{7}{5}=1\frac{2}{5}\).
3. В) \(\frac{7}{8}\cdot\frac{16}{3}=\frac{14}{3}=4\frac{2}{3}\).
4. Г) \(\frac{3}{2}\cdot\frac{2}{9}=\frac{1}{3}\).
5. Д) \(\frac{1}{7}\cdot\frac{107}{7}=\frac{107}{49}=2\frac{9}{49}\).
6. Е) \(\frac{1}{8}\cdot\frac{152}{9}=\frac{19}{9}=2\frac{1}{9}\).
7. Ж) \(\frac{3}{7}\cdot\frac{7}{3}=1\).
8. З) \(\frac{8}{7}\cdot\frac{49}{16}=\frac{7}{2}=3\frac{1}{2}\).
9. И) \(\frac{9}{2}\cdot\frac{14}{5}=\frac{63}{5}=12\frac{3}{5}\).
10. К) \(\frac{9}{2}\cdot\frac{14}{45}=\frac{7}{5}=1\frac{2}{5}\).
