197. Вычислите: 1) 8 4/15 + 2 11/15; 2) 4 5/9 + 3 7/9; 3) 1 − 14/23; 4) 6 − 3 4/9; 5) 9 5/12 − 4 7/12; 6) 24 11/36 − 5 25/36.

1. \(8\frac4{15}+2\frac{11}{15}=10+\frac{15}{15}=11\).
2. \(4\frac59+3\frac79=7+\frac{12}{9}=8\frac13\).
3. \(1-\frac{14}{23}=\frac9{23}\).
4. \(6-3\frac49=2\frac59\).
5. \(9\frac5{12}-4\frac7{12}=5-\frac2{12}=4\frac56\).
6. \(24\frac{11}{36}-5\frac{25}{36}=19-\frac{14}{36}=18\frac{11}{18}\).

Ответ: 1) \(11\); 2) \(8\frac13\); 3) \(\frac9{23}\); 4) \(2\frac59\); 5) \(4\frac56\); 6) \(18\frac{11}{18}\).
