Пошаговое объяснение:

(14- ( 49 1/3 ; 16 - 14 : 8 1/6) *7))/1 17/18 * ( 1 59/70 +37/42+2 19/30)- 10 = 10 3/5

1) 49 1/3 : 16= 148/3 *1/16= 37/12= 3 1/12

2) 14 : 8 1/6= 14 * 6/49= 84/49= 1 5/7

3) 3 1/12 - 1 5/7= 37/12 - 12/7 = 259/84 -144/84=115/84 = 1 31/84

4) 1 31/84 * 7= 115/84 * 7= 115/12= 9 7/12

5) 14 - 9 7/12= 4 5/12

6) 1 59/70 +37/42+ 2 19/30= 129/70 +37/42 + 79/30 = 387/210 + 185/210 + +553/210= 1125/210 = 5 15/42

7) 1 17/18 * 5 15/42 = 35/18 * 1125/210= 375/ 36= 10 5/12

8) 10 5/12 - 10= 5/12

9)  4 5/12 : 5/12= 53/12 * 12/5= 53/5 = 10 3/5
