a) 3,0(2)=3 intregi 2/90=(90x3+2)/90=272/90=136/45
b) 17,1(11)=17 intregi(111-1)/990= 17 intregi 110/990=(990x17+110)/990 = 16940/990
c) 23,(4)=23 intregi 4/9=(9x23+4)/9=211/9
d) 55,13(4)=55 intregi (134-13)/900=55 intregi 121/900=(900x55+121)/900=49621/900
e) 7,9(7)=7 intregi(97-9)/90=7 intregi88/90=(90x7+88)/90=718/90
f) 24,35(40)=24 intregi(3540-35)/9900=
24 intregi 3505/9900 =(9900x24+3505)/9900=241105/9900
g) 31,0(36)=31 intregi 36/990=(990x31+36)/990=30726/990
h)17,24(78)=17 intregi (2478-24)/9900=17 intregi 2454/9900=
(9900x17+2454)/9900=170754/9900
