Пошаговое объяснение:
1) 2 3/6 - 3 2/6 = - 5/6
2) -3/5 - 1 1/3 = -9/15 - 1 5/15 = -1 14/15
3) 5 7/8 - (-2 5/12) = 5 21/24 + 2 10/24 = 7 31/24 = 8 7/24
4) -2 3/4 - (-4/7) = -2 21/28 + 16/28 = -2 5/28
5) 3 9/6 - 4 11/24 = 4 3/6 - 4 11/24 = 4 12/24 - 4 11/24 = 1/24
6) - 4 11/12 - (-11/18) = -4 11/12 + 11/18= -4 33/36 + 22/36 = -4 11/36
