Решение:
- 78 : 6 = (60 + 18) : 6 = 60 : 6 + 18 : 6 = 10 + 3 = 13
- 84 : 3 = (60 + 24) : 3 = 60 : 3 + 24 : 3 = 20 + 8 = 28
- 57 : 3 = (30 + 27) : 3 = 30 : 3 + 27 : 3 = 10 + 9 = 19
- 62 : 2 = (60 + 2) : 2 = 60 : 2 + 2 : 2 = 30 + 1 = 31
- 74 : 2 = (70 + 4) : 2 = 70 : 2 + 4 : 2 = 35 + 2 = 37
- 75 : 5 = (50 + 25) : 5 = 50 : 5 + 25 : 5 = 10 + 5 = 15
- 48 : 3 = (30 + 18) : 3 = 30 : 3 + 18 : 3 = 10 + 6 = 16
- 24 : 3 = 8
