70/45.Stabiliti cate numere rationale diferite se afla in acest sir:
Exemplu:
0,4=4/10=2/5
6/-4=-6/4=-3/2
Dau coroana!!!!

Answer 1

0,4=4/10=2/5
6/-4=-6/4=-3/2
2,4=24/10=12/5
-1,500=-1500/1000=15/10=3/2
1 intreg 1/2=13/2
0,3(8)=(38-3)/90=35/90=7/18
-6/15=-2/5
14/36=7/18
-2=-2/1
12/-6=-12/6=-2
1,(5)=(15-1)/9=14/9
4/10=2/5
0,38(8)=(388-38)/900=350/900=35/90=7/18
14/35=2/5
15/10=3/2
3/-2=-3/2
-0,2=-2/10=-1/5
70/45=14/9
nr.rationale diferite sunt:
2/5,-2/5, -3/2, 12/5, 3/2, 13/2, 7/18, 14/9, -1/5
deci sunt 9 nr rationale diferite
