Bonjour
a. 22/5 = (22 x 2) / (5 x 2) = 44/10
9/2 = (9 x 5) / (2 x 5) = 45/10
Donc : 22/5 < 9/2
b. - 9/7 = (- 9 x 2) / (7 x 2) = - 18/14
- 13/2 = (- 13 x 7) / (2 x 7) = - 91/14
Donc :
- 9/7 > - 13/2
c. - 8/5 = (- 8 x 3) / (5 x 3) = - 24/15
- 11/3 = (- 11 x 5) / (3 x 5) = - 55/15
Donc : - 8/5 > - 11/3.
