Bonjour
a. 9/4
6/2 = (6 x 2) / (2 x 2) = 12/4
Donc : 9/4 < 6/2
b. 8/9
2/3 = (2 x 3) / (3 x 3) = 6/9
Donc : 8/9 > 2/3
c. 45/16
10/4 = (10 x 4) / (4 x 4) = 40/16
Donc : 45/16 > 10/4
d. 35/63
5/7 = (5 x 9) / (7 x 9) = 45/63
Donc : 35/63 < 5/7
e. 3,2/5 = (3,2 x 2) /(5 x 2) = 6,4/10
6,04/10
Donc :
3,2/5 > 6,04/10
f. 10/210 = (10 x 2) / (210 x 2) = 20/420
3/420
Donc : 10/210 > 3/420
g. 0,7/12 = (0,7 x 3) / (12 x 3) = 2,1/36
2,4/36
Donc : 0,7/12 < 2,4/36
h. 2/12
6 = (6 x 12) / (1 x 12) = 72/12
Donc : 2/12 < 6.
