Пошаговое объяснение:

1.

1) -1 5/11 + (-6 6/11) = -1 5/11 - 6 6/11 = -7 11/11 = -8

2) -3/7 + (-1 4/7) = -3/7 - 1 4/7 = -1 7/7 = - 2

3) -8 + (-2) = -8 - 2 = -10

2.

1) -5 9/17 + (-4 8/17) = -5 9/17 - 4 8/17 = -9 17/17 = -10

2) -4/15 + (-4 14/15) = -4/15 - 4 14/15 = -4 18/15 = -5 3/15 = -5 1/5

3) -10 + (-5 1/5) = -10 - 5 1/5 = -15 1/5.

3.

1) -1 2/7 + (-3 5/7) = -1 2/7 - 3 5/7 = -4 7/7 = -5

2) -5 + (-8 5/9) = -5 - 8 5/9 = -13 5/9.

4.

1) -1 4/9 + (-6 5/9) = -1 4/9 - 6 5/9 = -7 9/9 = -8

2) -3 2/3 + (-8) = -3 2/3 - 8 = -11 2/3.
