Ответ:
3 29/30
Пошаговое объяснение:
1) -3 3/5 - 2 1/3 = -3 9/15 - 2 5/15 = -5 14/15
2) -5 14/15 + 4 8/15 = -1 6/15 = -1 2/5
3) -1 2/5 - 1 5/6 = -1 12/30 - 1 25/30 = -2 37/30 = -3 7/30
4) -3 7/30 - (-6 7/10) = -3 7/30 + 6 7/10 = -3 7/30 + 6 21/30 = 3 14/30
5) 3 14/30 + 1/2 = 3 14/30 + 15/30 = 3 29/30
