Сравни. реши.: 72÷2 ; 72÷3 ; 42÷ 2 ;42÷3 ; 52÷ 2 ; 53÷ 3 ; 62÷2 ; 62÷3 ; 82÷2 ; 82÷3.

Answer 1

72:2=36  72:3=24 (ес ли делитель увеличить на 1 .то уменьшается частное в данном случае на 12) или в 1.5 раза
42:2=21  42:3=14
52:2=26 52:3= 17 1/3 (17 оста 1)наверно тут 54:2=27 54;3=18
62:2=31 62:3=20 2/3       (20  остат2)(66:2=33 66:3=22)
82:2=41 82:3=27 1/3  (27 ост1)

Comparing and Solving Division Problems

Let's compare and solve the given division problems:

1. 72 ÷ 2: - 72 ÷ 2 = 36 - Source: 2. 72 ÷ 3: - 72 ÷ 3 = 24 - Source: 3. 42 ÷ 2: - 42 ÷ 2 = 21 - Source: 4. 42 ÷ 3: - 42 ÷ 3 = 14 - Source: 5. 52 ÷ 2: - 52 ÷ 2 = 26 - Source: 6. 53 ÷ 3: - 53 ÷ 3 = 17.67 - Source: 7. 62 ÷ 2: - 62 ÷ 2 = 31 - Source: 8. 62 ÷ 3: - 62 ÷ 3 = 20.67 - Source: 9. 82 ÷ 2: - 82 ÷ 2 = 41 - Source: 10. 82 ÷ 3: - 82 ÷ 3 = 27.33 - Source: In summary, the results of the division problems are as follows: - 72 ÷ 2 = 36 - 72 ÷ 3 = 24 - 42 ÷ 2 = 21 - 42 ÷ 3 = 14 - 52 ÷ 2 = 26 - 53 ÷ 3 = 17.67 - 62 ÷ 2 = 31 - 62 ÷ 3 = 20.67 - 82 ÷ 2 = 41 - 82 ÷ 3 = 27.33
