Answer 2

Răspuns:

24 ÷ a = 8 ÷ 2

24 ÷ a = 4

a = 24 ÷ 4

a = 6

3 × a = 3 × 3 × 2

3 × a = 9 × 2

3 × a = 18

a = 18 ÷ 3

a = 6

54 ÷ a = 3 × 3

54 ÷ a = 9

a = 54 ÷ 9

a = 6

5 × a = 3 × 5

5 × a = 15

a = 15 ÷ 5

a = 3

42 ÷ a = 3 × 2

42 ÷ a = 6

a = 42 ÷ 6

a = 7

4 × a = 34 - 6

4 × a = 28

a = 28 ÷ 4

a = 7

7 × a = 84 - 42

7 × a = 42

a = 42 ÷ 7

a = 6

70 ÷ a = 5 × 2

70 ÷ a = 10

a = 70 ÷ 10

a = 7
