1 = (1 x 18) / (1x 18) = 18/18
1/3 = (1 x 6) / (3 x 6) = 6/18
2/6 = (2 x 2) / (9 x 2) = 4/18
9/2 = (9 x 9) / (2 x 9) = 81/18
Donc :
9/2 > 1 > 1/3 > 2/6 > 0

25/4 = (25 x 7) / (4 x 7) = 175/28
3/7 = (3 x 4) / (7 x 4) = 12/28
3/2 = (3 x 14) / (2 x 14) = 42/28
5/14 = (5 x 2) / (14 x 2) = 10/28
1 = (1 x 28) / (1 x 28) = 28/28
Donc :
5/14 < 3/7 < 1 < 3/2 < 25/4.
