Пошаговое объяснение:

1) = -8 1/3 + 0,5 = -8 1/3 + 1/2 = -(8 2/6 - 3/6) = -7 5/6

2) = 8,8 - 8 1/7 = 8 4/5 - 8 1/7 = 8 28/35 - 8 5/35 = 23/35

3) = -16,4 + 8 2/7 = -16 2/5 + 8 2/7 = -(16 14/35 - 8 10/35) = -8 4/35

4) = -19,4 + 9 1/5 = -19,4 + 9,2 = -10,2

5) = -19,4 + 13 1/3 = -19 2/5 + 13 1/3 = -(19 6/15 - 13 5/15) = -6 1/15

6) = 5,7 - 8 1/9 = 5 7/10 - 8 1/9 = -(8 10/90 - 5 63/90) = -2 37/90
