bonjour vous pouvez m'aider svp consignes : complète les empilement en respectant la règle suivant ​

Bonjour

pyramides multiplicative :

• 1/2 x 2/3 = (1 x 2)/(2 x 3) = 1/3

• 2/3 x 3/4 = (2 x 3)/(3 x 4) = 2/4 = 2/(2 x 2) = 1/2

• 3/4 x 4/5 = (3 x 4)/(4 x 5) = 3/5

• 1/3 x 1/2 = 1/(2 x 3) = 1/6

• 1/2 x 3/5 = (1 x 3)/(2 x 5) = 3/10

• 1/6 x 3/10 = (1 x 3)/(6 x 10) = 3/(2 x 3 x 10) = 1/20

1/20

1/6 | 3/10

1/3 | 1/2 | 3/5

1/2 | 2/3 | 3/4 | 4/5

• 1/2 x ? = 5/3

? = 5/3 / 1/2

? = 5/3 x 2

? = 10/3

• 3/4 x ? = 1/5

? = 1/5 / 3/4

? = 1/5 x 4/3

? = 4/15

• 10/3 x 3/4 = 10/4 = (2 x 5)/(2 x 2) = 5/2

• 5/3 x 5/2 = 25/6

• 5/2 x 1/5 = 1/2

• 25/6 x 1/2 = 25/12

25/12

25/6 | 1/2

5/3 | 5/2 | 1/5

1/2 | 10/3 | 3/4 | 4/15
