Пошаговое объяснение:

12 - 1\7  = 11 7/7 - 1/7 = 11 6/7

21 - 4\13  = 20 13/13 - 4/13 = 20 9/13

45 - 23\43  = 44 43/43 - 23/43 = 44 20/43

13 - 41\70  = 12 70/70 - 41/70 = 12 29/70

36 - 7\53  = 35 53/53 - 7/53 = 35 46/53

35 - 34\71  = 34 71/71 - 34/71 = 34 37/71

46 - 53\62 = 45 62/62 - 53/62 = 45 9/62
