Sagot :
Bjr, voici ma réponse :
c) 42/30 = 7/5 = 1,4
55/77 = 5/7 = 0.714285
35/70 = 5/10 = 0,5
d) 250/330 = 75/100 = 0,75
102/54 = 17/9 = 1,8
105/350 = 21/70 = 3/10 = 0,3
e) 108/81 = 12/9 = 4/3 = 1,3
125/65 = 25/13 = 19.10 = 1,9
420/360 = 70/60 = 7/6 = 1,16
...
Voilà, j'espère que ça t'aide ! =)

Réponse:
Bonsoir, voici le raisonnement détaillé :
Explications étape par étape:
A = 42/30
A = 7×6/(5×6)
A = 7/5
B = 55/77
B = 5×11/(7×11)
B = 5/7
C = 35/70
C = 1×35/(2×35)
C = 1/2
D = 250/330
D = 25×10/(33×10)
D = 25/33
E = 102/54
E = 17×6/(9×6)
E = 17/9
F = 105/330
F = 7×15/(22×15)
F = 7/22
G = 108/81
G = 4×27/(3×27)
G = 4/3
H = 125/65
H = 25×5/(13×5)
H = 25/13
I = 420/360
I = 7×60/(6×60)
I = 7/6
Voilà. J'espère t'avoir aidé.
Bonne journée.
