We can equate both ratios to get the following:
[tex]\frac{8}{24}=\frac{12}{28}[/tex]then, if we cross multiply, we have:
[tex]\begin{gathered} \frac{8}{24}=\frac{12}{28} \\ \Rightarrow8(28)=12(24) \\ \Rightarrow224=288 \end{gathered}[/tex]we have that 224 equals 288, which is false, therefore, the two ratios are not proportional
