Bonjour je suis en 4e et j’ai vraiment besoin d’aide pour ces 2 exercices sur les fractions merci beaucoup !

Bonjour,

1)

6/16 = (2 x 3) / (2 x 8) = 3/8

30/35 = (5 x 6) / (5 x 7) = 6/7

3/30 = (3 x 1) / (3 x 10) = 1/10

3/18 = (3 x 1) / (3 x 6) = 1/6

55/60 = (5 x 11) / (5 x 12) = 11/12

6/15 = (3 x 2) / (3 x 5) = 2/5

25/30 = (5 x 5) / (5 x 6) = 5/6

4/8 = (4 x 1) / (4 x 2) = 1/2

4/32 = (4 x 1) / (4 x 8) = 1/8

22/24 = (2 x 11) / (2 x 12) = 11/12

5/40 = (5 x 1) / (5 x 8) = 1/8

4/36 = (4 x 1) / (4 x 9) = 1/9
