Ответ:
а) \(5\frac{2}{15}+3\frac{5}{12}=8+\frac{8}{60}+\frac{25}{60}=8\frac{11}{20}\).
б) \(9\frac{4}{21}-4\frac{11}{14}=5+\frac{8}{42}-\frac{33}{42}=4\frac{17}{42}\).
в) \(5\frac{13}{35}+2\frac{13}{14}=7+\frac{26}{70}+\frac{65}{70}=8\frac{3}{10}\).
г) \(5\frac{5}{33}-4\frac{7}{22}=1+\frac{10}{66}-\frac{21}{66}=\frac{55}{66}=\frac{5}{6}\).
Ответ: а) 8 11/20; б) 4 17/42; в) 8 3/10; г) 5/6.
