2,(6) transformam in fractie ordinara:2,(6)=26-2/9 = 24/9 care se simplifica prin 3 = 8/3
1,2= 12/10 care se simplifica prin 2 = 6/53x=3/3x
3/3x - 6/5 = 8/3
3/3x = 8/3 + 6/5 aflam un multiplu comun pentru 3 si 5 (15)
3/3x = 40/15 + 18/15
3/3x = 58/15 |:3
58/15 :3/1 = 58/15 × 1/3 = 58/45
(sau 1/1x) = 58/45
sper ca e ok, m-am cam incurcat, nuj daca e corect dar sa speram
