fractii zecimale:
2,3=23/10
3,2=32/10
2,466=2466/1000
5,77=577/100
9,5=95/10
23,21=2321/100
7,12=712/100
5,8=58/10
56,7=567/10
1,4=14/10
fractii periodice simple:
1,(3)=13-1/9=12/9
0,(66)=66/99
4,(890)=4890-4/999=4886/999
0,(76)=76/99
4,(8)=48-4/9=44/9
10,(10)=1010-10/99=1000/99
7,(9)=79-7/9=72/9
0,(691)=691/999
3,(3)=33-3/9=30/9
5,(12)=512-5/99=507/99
8,(90)=890-8/99=882/99
fractii periodice mixte:
0,1(1)=11-1/90=10/90
2,0(4)=204-20/90=184/90
1,11(6)=1116-111/900=1005/900
9,3(93)=9393-93/990=9300/990
-> si aici faci la fel cu toate (periodice mixte)
