Answer:
4.5 per package
Explanation:
Though they give us 4 different pairs of values on the table, we only need 1 pair to solve this question. For simplicity, lets chose the pair of whole numbers:
54 : 12
This is the ration of servings to packages, or the servings per package.
To get our answer, we must find how many servings per 1 package, so we need to divide by 12:

=
4.5 : 1
This means that there are 4.5 servings per 1 package!
Hope this helps!
