Пошаговое объяснение:
-6/11+(-1/11) = -6/11 - 1/11 = -7/11
-1/27+13/36 = -4/108 + 39/108 = 35/108
-11/24+5/12 = -11/24 + 10/24 = -1/24
4 2/7+(-1 4/5) = 4 10/35 - 1 28/35 = 3 45/35 - 1 28/35 = 2 17/35
-6 5/6+3 5/8 = -6 20/24 + 3 15/24 = -3 5/24
-5/14+7/10 = -25/70 + 49/70 = 24/70
-1 3/8-1/4 = -1 3/8 - 2/8 = -1 5/8
-7,62-7,62 = -15,24
4,1-(-1,8+2,5) = 4,1 + 1,8 - 2,5 = 3,4
(14,5-85)+55,5 = 14,5 - 85 + 55,5 = -15
