What is the proportion? Determine which statement is a true proportion. $1.24/5oz = $1.86/7.5oz

This is not a true proportion.

Step-by-step explanation:

To determine if any proportion is true, we cross multiply. If the results from both sides are equal, then we have a true proportion. We'll start by multiplying the numerator from the first side by the denominator on the second.

1.24*7.5 = 9.375

Now we do it again with the denominator from the first side and the numerator from the second.

5*1.86 = 9.3

Technically, these are not the exact number. Therefore, this is not a proportion.
