Ответ:
1. 1 целая
2. 6 целых 5/7
3. 4 целых 3/10
4. 2 целых 4/5
Пошаговое объяснение:
3/8+5/8 = (3+5)/8 = 8/8 = 1
1/7+2(2/7+3) = 1/7 + 2*3 2/7 = 1/7 + 2*23/7 = 1/7 + 46/7 = 47/7 = 6 5/7
9-(5-3/10) = 9 - (4 10/10 - 3/10) = 9 - 4 7/10 = 4 3/10
4/5+2-(4/5-3/5)+1/5 = 4/5 + 2 - 1/5 + 1/5 = 4/5 + 2 = 2 4/5
