Question

A jar holds 80 fluids ounces of juice. The label says the jar has 10 servings. How many fluid ounces are needed for 80 servings?

Answer 1

640 fl oz

Explanation:

80 divided by 10 is 8. So each serving for a jar that hold 80 fl oz contains 8 fl oz.

So you would multioply 80 by 8 to find the amount of juice needed for 80 servings. 80*8= 640

Answer 2

80 ounces = 10 servings

Multiply both sides by 8:
8(80) ounces = 80 servings
640 ounces = 80 servings
