1. 1 целая 1/3
2. 2 целых 1/28
3. 5 целых 25/63
4. 2/3
Пошаговое объяснение:
1. 4 2/5 : (7/10 + 2 3/5) = 22/5 : 33/10 = 22/5 * 10/33 = 4/3 = 1 1/3
2. (7/15 + 4/5) : 3 1/9 = 19/15 : 28/9 = 19/15 * 9/28 = 57/28 = 2 1/28
3. (3/7 - 1/21) * 14 1/6 = 8/21 * 85/6 = 340/63 = 5 25/63
4. (8 1/3 : 2) : (1 9/10 + 4 7/20) = (25/3 * 1/2) : (19/10 + 87/20) =
25/6 : 25/4 = 25/6 * 4/25 = 4/6 = 2/3
