ответ: 4 5/12
Объяснение:1) 49 1/3 / 16 = 3 1/12
2) 14 / 8 1/6 = 1 5/7
3) 3 1/12 - 1 5/7 = 1 31/84
4) 7 * 1 31/84 = 9 7/12
5) 14 - 9 7/12 = 4 5/12
14 - 7 · (49 1/3 : 16 - 14 : 8 1/6) = 4 5/12
1) 49 1/3 : 16 = 148/3 · 1/16 = (37·1)/(3·4) = 37/12 = 3 1/12
2) 14 : 8 1/6 = 14 : 49/6 = 14 · 6/49 = (2·6)/7 = 12/7 = 1 5/7
3) 3 1/12 - 1 5/7 = 3 7/84 - 1 60/84 = 2 91/84 - 1 60/84 = 1 31/84
4) 7 · 1 31/84 = 7 · 115/84 = (1·115)/12 = 115/12 = 9 7/12
5) 14 - 9 7/12 = 13 12/12 - 9 7/12 = 4 5/12
ответ: 4 целых 5/12.
