Ответ:
- а) \(\frac{1}{8}+\frac{11}{12}=\frac{3}{24}+\frac{22}{24}=\frac{25}{24}=1\frac{1}{24}\).
б) \(\frac{7}{12}-\frac{7}{18}=\frac{21}{36}-\frac{14}{36}=\frac{7}{36}\).
в) \(\frac{15}{22}\cdot\frac{33}{40}=\frac{15\cdot3}{2\cdot40}=\frac{9}{16}\).
г) \(7\frac{1}{3}:4\frac{7}{12}=\frac{22}{3}:\frac{55}{12}=\frac{22}{3}\cdot\frac{12}{55}=\frac{8}{5}=1\frac{3}{5}\).
Ответ: а) \(1\frac{1}{24}\); б) \(\frac{7}{36}\); в) \(\frac{9}{16}\); г) \(1\frac{3}{5}\).
