In order to convert the decimal numbers to fractions, let's multiply and divide the number by 10 to the power of the number of decimal places. So we have:
[tex]\begin{gathered} 0.20=0.20\cdot\frac{100}{100}=\frac{20}{100}=\frac{2}{10}=\frac{1}{5} \\ \\ 0.33=0.33\cdot\frac{100}{100}=\frac{33}{100} \\ \\ 0.25=0.25\cdot\frac{100}{100}=\frac{25}{100}=\frac{5}{20}=\frac{1}{4} \end{gathered}[/tex]So the corresponding fractions are 1/5, 33/100 and 1/4.
