Answer 1

2,36 =236/100=59/25
1,08=108/100=27/25
-1,5=-15/10=-3/2
 0,(6)=6/9=2/3
 -1,(15)=-(115-1)/99=-114/99=-38/33
2,3(6)=(236-23)/90=213/90=71/30
0,12(3)=(123-12)/900=111/900=37/30
0,1(23)=(123-1)/990=122/990=61/495
2,1(15)=(2115-21)/990=2094/990=698/330=349/165
2,11(51) =(21151-211)/9900=20940/9900=698/330=1745/825=349/165
-1,2(333)=-(12333-12)/9990=-12321/9990=1369/1110=37/30
0,12(12)=(1212-12)/9900=1200/9900=12/99=4/33
0,164646...=164646/1000000=82323/500000
