Пошаговое объяснение:

1) -5,6 - 3 11/15 = -56/10 - 56/15 = -168/30 - 112/30 = -280/30 = -28/3 = -9 1/3

2) 4 7/30 - 6 1/20 = 4 14/60 - 6 3/60 = 4 14/60 - 5 63/60 = -1 49/60

3) -1 17/60 - (-8,8) = -1 17/60 + 8 8/10 = -1 17/60 + 8 48/60 = 7 31/60

4) -9 1/3 - (-1 49/60) = -9 20/60 + 1 49/60 = -8 80/60 + 1 49/60 = -7 31/60

5) -7 31/60 + 7 31/60 = 0
