Answer 1

What the person said above me

Answer 2

This represents a proportional relationship, the ratios are equivalent, and the constant of proportionality is 7.7.

Explanation:

Since we know that six cell phones weigh 46.2 oz, we can divide 46.2 by 6 to find the weight of each, so 46.2/6=7.7.

We also know that fourteen cell phones weigh 107.8 oz, so we divide 107.8 by fourteen and get 7.7 as well.

Since both ratios equal 7.7 oz per cell phone, the ratios are equal and the relationship is proportional.
