Answer:
<h2>They are proportional.</h2>
Step-by-step explanation:
The ratios are
and
To demonstrate if they are proportional, both must be equivalent. So, let's find out:
If we simplify each fraction, we have:
As you can see, both ratios are equivalent, this mean that they are proportional, and the constant of proportionality is .
Therefore, they are proportional.
