Bonsoir aidez moi merci Simplifier le plus possible avec etapes les fractions 15/60 5/60 28/60 12/60 MERCI

15 / 60 = (15 x 1) / (15 x 4) = 1 /4

5 / 60 = (5 x 1) / (5 x 12) = 1 / 12

28 / 60 = (7 x 4) / (15 x 4) = 7 / 15

12 / 60 = (12 x 1) / (12 x 5) = 1 / 5

15/60 = 15 x 1 / 15 x 4 = 1/4
5/60 = 5 x 1 / 5 x 12 = 1/12
28/60 = 4 x 7 / 4 x 15 = 7/15
12/60 = 12 x 1 / 12 x 5 = 1/5
