Ответ:
а) \(\frac{7}{8}+1\frac{3}{8}=\frac{7}{8}+\frac{11}{8}=\frac{18}{8}=2\frac{1}{4}\).
б) \(5\frac{11}{14}-2\frac{2}{7}=5\frac{11}{14}-2\frac{4}{14}=3\frac{7}{14}=3\frac{1}{2}\).
в) \(\frac{5}{6}:3\frac{1}{3}=\frac{5}{6}:\frac{10}{3}=\frac{5}{6}\cdot\frac{3}{10}=\frac{1}{4}\).
г) \(\frac{4}{17}-\frac{51}{44}\cdot\frac{1}{3}=\frac{4}{17}-\frac{17}{44}=\frac{176}{748}-\frac{289}{748}=-\frac{113}{748}\).
Ответ: а) \(2\frac{1}{4}\); б) \(3\frac{1}{2}\); в) \(\frac{1}{4}\); г) \(-\frac{113}{748}\).
