14,(6) = 14 + 0,(6) = 14 + 6/9 = 14 + 2/3

0,3(25) = 0 + 3/(1010) + 25/(1010*10-1) = 3/10 + 25/999

11,78(9) = 11 + 78/(1010) + 9/(1010*10-1) = 11 + 78/100 + 9/999

5,236 = 5 + 236/1000

43,(40) = 43 + 40/99

11,87 = 11 + 87/100

3,0(2) = 3 + 2/9

12,(54) = 12 + 54/99

0,00(7) = 0 + 7/90

11,35(80) = 11 + 35/100 + 80/999

9,(085) = 9 + 85/99

18,(75) = 18 + 75/99

32,03(5) = 32 + 3/10 + 5/99

95,3(451) = 95 + 3/10 + 451/999

1,(12345) = 1 + 12345/99999

73,456(5) = 73 + 456/1000 + 5/9999
