Пошаговое объяснение:
1) 4 1/6 - 2 5/6 = 3 7/6 - 2 5/6 = 1 2/6
2) 2 3/4 + 4 1/3 = 6 + 3/4 + 1/3 = 6 + 9/12 + 4/12 = 6 + 13/12 = 6 + 1 1/12 = 7 1/12
3) 5 3/4 - 4 1/3 = 1 + (3/4 - 1/3) = 1 + (9/12 - 4/12) = 1 5/12
4) 4 + 4 1/3 = 8 1/3
5) 4 - 2 3/5 = 3 5/5 - 2 3/5 = 1 2/5
6) 8 1/5 - 3 4/9 = 7 6/5 - 3 4/9 = 4 + (6/5 - 4/9) = 4 + (54/45 - 20/45) = 4 34/45
