Well first we must see if they are proportional.

46.2/6 = 10.7.8/14
7.7 = 7.7

They are proportional. The rate of proportion is 7.7 ounces per cellphone. Hope this helps!

Answer:

<h2>They have a proportional relationship, with a constant of proportionality of 7.7</h2>

Step-by-step explanation:

<em>A proportional relationship refers to the equivalence between two reasons, or two fractions.</em>

So, in this case, we have the two reasons.

<h3>First reason: </h3>

\frac{46.2 \ ounces }{6 \ cellphones}

<h3>Second reason:</h3>

\frac{107.8 \ ounces}{14 \ cellphones}

Now, to find if these reasons are proportional we just have to equalize them and find if both fractions have the same result:

\frac{46.2 \ ounces }{6 \ cellphones}=\frac{107.8 \ ounces}{14 \ cellphones}\\7.7=7.7

<em>As you can see, both fractions have the same result, this means that those reasons have a proportional relationship, and the constant of proportionality is 7.7.</em>
