5. Найдите разность: 1) 7 5/6 − 3 2/3; 2) 8 5/12 − 6 7/20; 3) 11 11/12 − 5 7/9; 4) 9 17/24 − 8 11/36.

1. \(7\frac{5}{6}-3\frac{2}{3}=7\frac{5}{6}-3\frac{4}{6}=4\frac{1}{6}\).
2. \(8\frac{5}{12}-6\frac{7}{20}=8\frac{25}{60}-6\frac{21}{60}=2\frac{4}{60}=2\frac{1}{15}\).
3. \(11\frac{11}{12}-5\frac{7}{9}=11\frac{33}{36}-5\frac{28}{36}=6\frac{5}{36}\).
4. \(9\frac{17}{24}-8\frac{11}{36}=9\frac{51}{72}-8\frac{22}{72}=1\frac{29}{72}\).

Ответ: 1) \(4\frac{1}{6}\); 2) \(2\frac{1}{15}\); 3) \(6\frac{5}{36}\); 4) \(1\frac{29}{72}\).
