Answer: 4.4 + (4 x 1/4 + 8.6) = 14
Step-by-step explanation: Because starting inside the parenthesis, 4 times 1/4 = 1. Then 8.6 plus 1 = 9.6. Finally, 9.6 plus 4.4 which equals 14. :)

Answer:
4.5 per package
Step-by-step 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!
