Bonsoir
exercice 2
e = 3+1/2=6/2+1/2=7/2
donc 7/3+1/2=7/7/2=7*2/7=14/7=2
2*1/7=2/7
7/2*2/7=14/14=1
exercice 3
a/ 3/5-1/2=6/10-5/10=1/10*5/2=5/20=1/4
b/ 3-2/3=9/3-2/3=7/3
4/3*7=28/3 et 7/3:28/3=7/3*3/28=21/84=1/4
c/ 8/3-2/3=6/3=2
2+8/7=14/7+8/7=22/7
d/ -2/5+5/2=-4/10+25/10=21/10
-3/4+1/2=-3/4+2/4=-1/4
21/10:-1/4=21/10*-4/1=-84/10=-42/5
3/ inverse de b=4
opposé de d=42/5
b+d=1/4+(-42/5)=5/20-168/20=-163/20
c*d= 22/7*-42/5=-924/35=-132/5
*veut dire multiplier
