Explicație pas cu pas:

6 × 4 = 2 × 3 × a

24 = 6 × a

6 × a = 24

a = 24 ÷ 6

a = 4

6 × 4 = 2 × 3 × 4

8 × 3 = 4 × a × 2

24 = 4 × 2 × a

24 = 8 × a

8 × a = 24

a = 24 ÷ 8

a = 3

8 × 3 = 4 × 3 × 2

6 × 2 = a × 3 × 2

12 = a × 6

a × 6 = 12

a = 12 ÷ 6

a = 2

6 × 2 = 2 × 3 × 2

2 × 8 = 2 × 2 × a

16 = 4 × a

4 × a = 16

a = 16 ÷ 4

a = 4

2 × 8 = 2 × 2 × 4

9 × 2 = 3 × a × 2

18 = 3 × 2 × a

18 = 6 × a

6 × a = 18

a = 18 ÷ 6

a = 3

9 × 2 = 3 × 3 × 2

6 × 5 = a × 5 × 2

30 = a × 10

a × 10 = 30

a = 30 ÷ 10

a = 3

6 × 5 = 3 × 5 × 2
