bonjour
1/3 + 5/12 = 4/12 + 5/12 = 9/12 simplifié par 3 = 3/4
43/20 - 2 = 43/20 - 40/20 = 3/20
7/4 - 2/5 = 35/20 - 8/20 = 27/20
3/7 × 5/4= 15/28
20/9 × 21/8= 420/28 = 15
8/9 × 7 = 56/9
5/3 ÷11/2 = 5/3 × 2/11= 10/33
9/2: 5 = 9/2 x 1/5 = 9/10
40/7 ÷ 8/42 = 40/7 x 42/8 = 1680/56 = 30
/!\ Attention aux priorité opératoire !
A = 3/2 - 1/2 × 7/5 = 3/2 - 7/10 = 15/10 - 7/10 = 8/10 = 4/5
