Answer 1

a) 1,2=12/10=6/5;
0,75=3/4;
4,12=412/100=103/25;
b)0,(3)=3/9=1/3;
2,36=236/100=59/25;
4,125=4125/1000=33/8;
c)0,3(12)=(312-3)/990=309/990=
103/330;
8,0(6)=(806-8)/90=798/90=133/15;
12,12(345)=(1212345-1212)/99900=
1211133/99900=403711/33300

Answer 2

1,2=$\frac{12}{10}$
0,75=$\frac{75}{100}$
4,12=$\frac{412}{100}$
0,(5)=$\frac{5}{9}$
2,36=$\frac{236}{100}$
4,125=$\frac{4125}{1000}$
0,3(12)=$\frac{309}{990}$
8,0(6)=$\frac{799}{900}$
12,12(345)=$\frac{1211133}{99900}$
