Bonjour

Compléter avec le nombre qui convient :

5 x ... = 30

... = 30/5

... = (6 x 5)/5

... = 6

5 x 6 = 30

7 x ... = 25

... = 25/7

7 x 25/7 = 25

16/9 x ... = 16

... = 16 x 9/16

... = 16/16 x 9

... = 9

16/9 x 9 = 16

10/11 x ... = 20

... = 20 x 11/10

... = 20/10 x 11

... = (2 x 10)/10 x 11

... = 2 x 11

... = 22

10/11 x 22 = 20

1/4 x ... = 3/4

... = 3/4 x 4

... = 4/4 x 3

... = 3

1/4 x 3 = 3/4

2/5 x ... = 2/5

... = 2/5 x 5/2

... = (2 x 5)/(2 x 5)

... = 1

2/5 x 1 = 2/5

... x 4 = 28

... = 28/4

... = (7 x 4)/4

... = 7

7 x 4 = 28

... x 6 = 21

... = 21/6

... = (3 x 7)/(3 x 2)

... = 7/2

7/2 x 6 = 21

... x 17/8 = 17

... = 17 x 8/17

... = 17/17 x 8

... = 8

8 x 17/8 = 17

... x 8/3 = 24

... = 24 x 3/8

... = (8 x 3 x 3)/8

... = 9

9 x 8/3 = 24

... x 1/3 = 2/3

... = 2/3 x 3

... = 3/3 x 2

... = 2

2 x 1/3 = 2/3

... x 1/3 = 2/6

... = 2/6 x 3

... = (2 x 3)/(2 x 3)

... = 1

1 x 1/3 = 2/6
