44 : 4 = (40 + 4) : 4 = 10 + 1 = 11
44 : 4 = (36 + 8) : 4 = 9 + 2 = 11
44 : 4 = (32 + 12) : 4 = 8 + 3 = 11
Проверка:
11 * 4 = (10 + 1) * 4 = 40 + 4 = 44
48 : 2 = (40 + 8) : 2 = 20 + 4 = 24
48 : 2 = (24 + 24) : 2 = 12 + 12 = 24
48 : 2 = (30 + 18) : 2 = 15 + 9 = 24
Проверка:
24 * 2 = (20 + 4) * 2 = 40 + 8 = 48
85 : 5 = (50 + 35) : 5 = 10 + 7 = 17
85 : 5 = (45 + 40) : 5 = 9 + 8 = 17
85 : 5 = (55 + 30) : 5 = 11 + 6 = 17
Проверка:
17 * 5 = (10 + 7) * 5 = 50 + 35 = 85
72 : 6 = (60 + 12) : 6 = 10 + 2 = 12
72 : 6 = (42 + 30) : 6 = 7 + 5 = 12
72 : 6 = (36 + 36) : 6 = 6 + 6 = 12
Проверка:
12 * 6 = (10 + 2) * 6 = 60 + 12 = 72
