bonjour
7/12 - 1 /6 = 7/12 - 2/12 = 5/12
5/11 - 3/22 = 10/22 - 3 /22 = 7 /22
18/17 - 5 /34 = 36/34 - 5/34 = 31/34
11/36 - 2/9 = 11/36 - 8/36 = 3 /36 = 1/12
1/24 + 3/8 + 5/4 = 1/24 + 9/24 + 30/24 = 40/24 = 5/3
3/40 + 18/20 + 7/10 = 3/40 + 36/40 + 28/40 = 67/40
7/0.6 + 7/60 = 70/60 + 7/60 = 77 /60
1/6 + 1 = 1 /6 + 6/6 = 7 /6
7 + 3/4 = 28/4 + 3 /4 = 31/4
5 - 1/3 = 15/3 - 1/3 = 14/3
6 + 2/3 = 18/3 + 2/3 = 20/3
allez continue, tu mets au même dénominateur
