Answer:
They are proportional.
Step-by-step explanation:
The ratios are
[tex]\frac{48}{72}[/tex] and [tex]\frac{6}{9}[/tex]
To demonstrate if they are proportional, both must be equivalent. So, let's find out:
[tex]\frac{48}{72}=\frac{6}{9}[/tex]
If we simplify each fraction, we have:
[tex]\frac{6}{9}=\frac{6}{9}\\\frac{2}{3}=\frac{2}{3}[/tex]
As you can see, both ratios are equivalent, this mean that they are proportional, and the constant of proportionality is [tex]\frac{2}{3}[/tex].
Therefore, they are proportional.
