1.
a) 2,4=24/10 /-->bara de la fractie in caz ca nu sti :)
0,25=25/100
8,102=8102/1000
b) 0,(2)=2/9
4,(27)=427-4/99=423/99
20,(123)=20123-20/999=20103/999
c) 0,2(45)=245-2/990=243/990
0,24(5)=245-24/900=221/900
7,0(5)=705-7/90=698/90
2.
a) 0,4=4/10=2/5 (simplificat prin 2)
0,25=25/100=1/4(simplificat prin 25)
8,375=8375/1000=1675/200 (prin 5)=335/40(tot prin 5)=67/8(fractie ireductibila)
b)0,(6)=6/9 (simplificam prin 3)=2/3
4,(27)=427-4/99=423/99(simplificam prin 9)=47/11(fractie ireductibila)
30,(123)=30123-30/999=30093/999(prin 3)=10031/333(fractie ireductibila)
c)0,6(54)=654-6/990=648/990(simplificam prin 9)=72/110(simplificam prin 2)=36/55
0,24(3)=243-24/900=219/900(prin 3)=73/300
3,0(6)=306-3/90=303/90(simplificat prin 3)=101/30
- toate sunt fractii ireductibile dar am pus doar ca sa iti dai seama :D(ex 2)
