8 × 4 = 32

P : 32 : 4 = 8

5 × 9 = 45

P : 45 : 9 = 5

7 × 6 = 42

P : 42 : 6 = 7

48 : 6 = 8

P : 6 × 8 = 48

72 : 8 = 9

P : 9 × 8 = 72

21 : 7 = 3

P = 7 × 3 = 21

8 × 4 = 32 => 32 : 4 = 8

5 × 9 = 45 => 45 : 9 = 5

7 × 6 = 42 => 42 : 6 = 7

48 : 6 = 8 => 8 × 6 = 48

72 : 8 = 9 => 9 × 8 = 72

21 : 7 = 3 => 3 × 7 = 21

SUCCES!!
