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.
