svp aidez moi pour la rentrée je ne comprends pas​

Bonjour

22/33 = (11 x 2) / (11 x 3) = 2/3

21/35 = (7 x 3) / (7 x 5) = 3/5

10/15 = (5 x 2) / (5 x 3) = 2/3

27/45 = (9 x 3) / (9 x 5) = 3/5

3/5

14/21 = (7 x 2) / (7 x 3) = 2/3

2/3

18/30 = (6 x 3) / (6 x 5) = 3/5

Donc :

22/33 = 10/15 = 14/21 = 2/3

21/35 = 27/45 = 18/30 = 3/5
