Bonjour, il y a deux exercices que je ne comprend pas. Merci de m'aider à faire l'ex. 57 et 60 s'il vous plaît. (c'est en urgence) ​

Bonsoir

57)

a. 45/54 = (9 x 5) / (9 x 6) = 5/6

b. 16/64 = (16 x 1) / (16 x 4) = 1/4

c. 4/24 = (4 x 1) / (4 x 6) = 1/6

d. 26/52 = (26 x 1) / (26 x 2) = 1/2

e. 72/48 = (24 x 3)  (24 x 2) = 3/2

f. 32/30 = (2 x 16) / (2 x 15) = 16/15

g. 2/100 = (2 x 1) / (2 x 50) = 1/5.

60)

a. 26/12 = 13/6 car (2 x 13) / (2 x 6) = 26/12

b. 95/15 = 19/3 car (19 x 5) / (3 x 5) = 95/15

c. 63/27 = 7/3 car (9 x 7) / (9 x 3) = 63/27

d. 17/19 = 85/95 car (17 x 5) / (19 x 5) = 85/95.

Réponse:

exercice 1:

a) 45/54=5/6

b)16/64=1/4

c)4/24=1/6

d)26/52=1/2

e)72/48=9/6=3/2

f)32/30=16/15

g)2/100=1/50
