1. (-352+28): (-3) 2. дробь (5/3-1/8)*6/37 3. 156-3,2: 0,2 4. дробь 7 2/3: (7/9-9/5)-2*1 1/4

Пошаговое объяснение:

1. -324:(-3) = 108

2. (40/24-3/24)*6/37 = 37/24*6/37 = 222/888 = 1/4

3. 156-16 = 140

4. 23/3:(35/45-81/45)-2*5/4 = 23/3:(-46/45)-10/4 - -1035/138-10/4 = -2070/276-690/276 - -2760/276 = -10
