12/18 = 2/3
28/49 = 4/7
3/15 = 1/5
10/18 = 5/9
21/28 = 3/4
200/220 = 10/11
2/8 = 1/4
21/36 = 7/12
56/64 = 7/8
63/77 = 9/11
60/44 = 15/11
25/75 = 1/3
48/32 = 3/2
27/63 = 3/7
63/75 = 7/15
15/24 = 5/8
34/22 = 17/11
56/16 = 7/2
8/16 = 1/2
27/51 = 9/17
12/27 = 4/9
22/20 = 11/10
36/42 = 6/7
28/24 = 7/6
70/490 = 1/7
124/62 = 2/1
J'espère que cela t'aide !
