14,8(3) = (1483-148 ) /90=1335 /90= 267/18=89/6

1,02(7) = (1027-102)/900= 925/900=37/ 36
 
0,24(54)= (2454-24)/9900=2430/9900=243/990=27/110

0,2(387)= (2387-2) / 9990= 2385/ 9990=477/ 1998 =159/666 = 53/ 222

14,8(3)=14 intregi (83-8)/90=14 intregi 75/90=(14x90+75)/90=1335/90=267/18=89/6

1,02(7)=1 intreg (27-2)/900=1 intreg 25/900=(1x900+25)/900=925/900=37/36

0,24(54)=(2454-24)/9900=2430/9900=27/110

0,2(387)=(2387-2)/9000=2385/9990=53/222
