Ответ:
- \(2\frac{1}{3}+1\frac{5}{6}=\frac{14}{6}+\frac{11}{6}=\frac{25}{6}=4\frac{1}{6}\).
- \(5\frac{3}{4}-2\frac{2}{3}=\frac{23}{4}-\frac{8}{3}=\frac{69}{12}-\frac{32}{12}=\frac{37}{12}=3\frac{1}{12}\).
- \(3\frac{1}{2}:1\frac{1}{5}=\frac{7}{2}:\frac{6}{5}=\frac{7}{2}\cdot\frac{5}{6}=\frac{35}{12}=2\frac{11}{12}\).
- \(4\frac{2}{7}:1\frac{1}{14}=\frac{30}{7}:\frac{15}{14}=\frac{30}{7}\cdot\frac{14}{15}=4\).
- \(6\frac{5}{8}+2\frac{3}{4}=6\frac{5}{8}+2\frac{6}{8}=9\frac{3}{8}\).
- \(7\frac{1}{3}-3\frac{5}{6}=\frac{44}{6}-\frac{23}{6}=\frac{21}{6}=3\frac{1}{2}\).
