0,24(56)=(2456-24)/9900=2432/9900=simplif.pana nu se mai poate=1216/4950=608/2475
0,5(4)=(54-5)/90=49/90
⇒608/2475+49/90=aduce⇒aducem la acelasi numitor
calculam c.m.m.m.c
2475=5²x3²x11
90=3²x5x2
[2475,90]=3²x5²x2x11=9x25x22=4950
pe urma amplificam fiecare fractie
4950:2475=2
4950:90=55
⇒608/2475+49/90=
(608x2+49x55)/4950=(1216+2695)/4950=3911/4950=0,79(01)
