1,8=18/10=9/5 (am simplificat prin 2)

2,25=225/100=9/4 (am simplificat prin 25)

8,(12)=8 intregi si 12/99=804/99=268/33 (am simplificat prin 3)

1,5(6)=1 intreg si (56-5)/90=1 intreg si 51/90=(90+51)/90=141/90=47/33 (am simplificat prin 3)

36,8=368/10=184/5 (am simplificat prin 2)

29,75=2975/100=119/4 (am simplificat prin 25)

4,(16)=4 intregi si 16/99=(4*99+16)/99=412/99

51,2(8)=51 intregi si (28-2)/90=51 intregi si 26/90=51 intregi si 13/45=2308/51

36,125=36125/1000=1445/4 (am simplificat prin 25)

 0,81(27)=(8127-81)/9900=8046/9900=447/550
