Bonjour


comparer :


9/4 et 6/2

6/2 = (6 x 2)/(2 x 2) = 12/4


9/4 < 12/4

Donc : 9/4 < 6/2


8/9 et 2/3

2/3 = (2 x 3)/(3 x 3) = 6/9


8/9 > 6/9

donc : 8/9 > 2/3


45/16 et 10/4

10/4 = (10 x 4)/(4 x 4) = 40/16


45/16 > 40/16

donc : 45/16 > 10/4


35/63 et 5/7

5/7 = (5 x 9)/(7 x 9) = 45/63


35/63 < 45/63

Donc : 35/63 < 5/7

Réponse:

a) 9/4 < 12/4

b) 8/9 > 6/9

c) 45/16 > 40/16

d) 35/63 < 45/63
