j'ai c'est fraction a simplifier 6/4 45/35, 48/36, 60/15, 258/384,8/10, 13/26, 18/27, 22/77.

6/4 = 2 x 3 / 2 x 2 = 3/2
45/35 = 5 x 9 / 5 x 7 = 9/7
48/36 = 12 x 4 / 12 x 3 = 4/3
60/15 = 15 x 4 / 15 x 1 = 4/1 = 4
258/384 = 6 x 43 / 6 x 64 = 43/64
8/10 = 2 x 4 / 2 x 5 = 4/5
18/27 = 9 x 2 / 9 x 3 = 2/3
22/77 = 11 x 2 / 11 x 7 = 2/7
