In order to find if the fractions are proportional, let's put both fractions in decimal form:
[tex]\begin{gathered} \frac{0.6}{0.5}\cdot\frac{2}{2}=\frac{1.2}{1}=1.2 \\ \frac{12}{10}\cdot\frac{0.1}{0.1}=\frac{1.2}{1}=1.2 \end{gathered}[/tex]The fractions have the same decimal form, therefore they are proportional.
