Step-by-step explanation:

Given that,

12 over 30 and 18 over 45

We need to tell whether the ratios are Proportional or Not Proportional.

[tex]\dfrac{12}{30}=\dfrac{2}{5}[/tex]

And

[tex]\dfrac{18}{45}=\dfrac{2}{5}[/tex]

The ratio for both fraction is same i.e. 2/5 Hence, each ratios are Proportional.
