Пошаговое объяснение:

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

-5/11 - (-5/11) = -5/11 + 5/11 = 0

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

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

1/6 - (+3) = 1/6 - 3 = 1/6 - 2 6/6 = -2 5/6

-5/12 - (-4) = -5/12 + 4 = -5/12 + 3 12/12 = 3 7/12
