3/2+2/5= 15/10 + 4/10 = 19/10
7/10-3/8 = 56/80 - 30/80 = 26/80 = 13/40
159/10-3/2 = 159/10 - 15/10 = 144/10
7/15-1/6 = 14/30 - 5/30 = 9/30 = 3/10
7/12+1/18 = 21/36 - 2/36 = 19/36
9/11+9/2 = 18/22 + 99/22 = 117/22
7/20+5/8 = 14/40 + 25/40 = 39/40
7/15-5/18= 126/270 - 75/270 = 51/270 = 17/90
9/8+2/9 = 81/72 +16/72 = 97/72
5-11-6 = -12
3/4+3 = 3/4 + 12/4 = 15/4
6+2/7 = 42/7 +2/7 = 44/7
3/32+9/8 = 3/32 + 36/32 = 39/32
3/7-5/49 = 21/49 -5/49 = 16/49
8/7-9/56= 64/56 - 9/56 = 55/56
7/10+9/4 = 28/40 +90/40 = 118/40 = 59/40
6-13/7 = 42/7 -13/7 = 29/7

fais pas a ttention a letoile au debut
7/12+1/18 = 21/36 - 2/36 = 19/36
7/10+9/4 = 28/40 +90/40 = 118/40 = 59/40
ils sont faux ces resultats
alors c quioi la reponse
7/12+1/18=21/36+2/36=23/36
7/10+9/4=14/20+45/20=59/20
