Explicație pas cu pas:
0,91(6) = (916-91)/900 =( 825/900)⁽⁽²⁵ = (825:25)/(900:25) = (33/36)⁽³ = 11/12
0,8(3) = (83-8)/90 = (75/90)⁽⁵ =(75:5)/(90:5) = (15/18)⁽³ =(15:3)/(18:3) = 5/6
0,41(6) = (416-41)/900 = (375/900)⁽²⁵= (375:25)/(900:25) = (15/36)⁽³ = 5/12
1,23(7) = (1237-123)/900 = (1114/900)⁽² = (1114:2)/(900:2) = 557/450
2,4(81) = (2481-24)/990 = (2457/990)⁽⁹ = (2457:9)/(990:9) = 273/110
0,0(27) = 27/990 = (27:9)/(990:9) = 3/110
