Bonjour !
9/5 =5/5 + 4/5 = 1 + 4/5
7/4 = 4/4 + 3/4 = 1 + 3/4
3/2 = 2/2 + 1/2 = 1 + 1/2
11/5 = 10/5 + 1/5 = 2 + 1/5
13/8 = 8/8 + 5/8 = 1 + 5/8
10/4 = 8/4 + 2/4 = 2 + 2/4
5/8 => plus petit que 1
10/3 = 9/3 + 1/3 = 3 + 1/3
8/6 = 6/6 + 2/6 = 1 + 2/6
19/6 = 18/6 + 1/6 = 3 + 1/6
16/5 = 15/5 + 1/5 = 3 + 1/5
37/10 = 30/10 + 7/10 = 3 + 7/10
J'espère t'avoir aidé. Bon courage !
