Bonjour!

Ex13

a. 17/25 = 34/50 = 68/100

b. 2/5 = 10/25 = 40/100

c. 1/10 = 2,5/25 = 10/100

d. 1/2 = 12,5/25 = 50/100

Ex14

a. 3/4 = 27/36

b. 5/7 = 25/35

c. 68/64 =34/32 = 17/16

d. 35/21 = 70/42 = 10/6

Ex15

a. 12/5 = 24/10

b. 54/25 = 216/100

c. 300/200 = 150/100

d. 542/5000 = 1084/10000

e. 40/50 = 80/100

f. 50/10000 = 5/1000

Voila! J'espere t'avoir aide! :D

Réponse :

Remarque: Le / correspond à la barre de fraction, donc il faudra le remplacer sur le devoir
