14. Вычислите: 1) 5 15/22 − 11/22; 2) 83 21/23 − 12/23; 3) 31 21/25 − 16/25; 4) 106 31/52 − 12/52.

1. \(5+\frac{15-11}{22}=5\frac2{11}\).
2. \(83+\frac{21-12}{23}=83\frac9{23}\).
3. \(31+\frac{21-16}{25}=31\frac15\).
4. \(106+\frac{31-12}{52}=106\frac{19}{52}\).

Ответ: 1) \(5\frac2{11}\); 2) \(83\frac9{23}\); 3) \(31\frac15\); 4) \(106\frac{19}{52}\).
