Explicație pas cu pas:
1,(3) = (13 - 1)/9 = 12/9
4,(6) = (46 - 4)/9 = 42/9
15,(2) = (152 - 15)/ 9 = 137/9
6,(23) =(623 - 6)/99 = 617/99
7,(63) = (763 - 7)/99 =756/99
0,(18) = 18/99
0,(108) = 108/999
5,(036) = (5036 - 5)/999 = 5031/999
1,2(3) = (123 - 12)/90 = 111/90
6,0(12) = (6012-60)/990 = 5952/990
0,01(4) = (14 - 1)/900 = 13/900
5,00(8) = (5008 - 500)/900 = 4508/900
16,40(81) = (164081 - 1640)/9900 = 162441/9900
0,3(102) = (3102 - 3)/9990 = 3099/9990
