1,5=1 \frac{5}{10} =1 \frac{1}{2} = \frac{3}{2}  

3,(6)=3 \frac{6}{9} =3 \frac{2}{3} = \frac{11}{3}  

1,2(6)=1 \frac{26-2}{90} =1 \frac{23}{90} = \frac{113}{90}  

0,32(47)=32 \frac{3247-32}{9900} =32 \frac{3215}{9900} = 32 \frac{643}{1980} = \frac{32*1980+643}{1980} = \frac{63360+643}{1980}  

= \frac{63003}{1980} = \frac{21001}{660}
