Debbie needs to fill juice cups for her little brothers birthday party. There are 20 juice cups and each juice cup holds 10 fluid ounces. The juice comes in 1-gallon bottles. How many 1-gallon bottles of juice will Debbie need to purchase?

Answer 1

If she has 20 juice cups that each fill 10 ounces, then you can do the equation #20*10# to find out that you need #200# ounces of juice. Now, you must find out how many ounces are in a gallon, so we are going to break it down.

There are 8oz in a cup. 2 cups in a pint, so 16oz in a pint. 2 pints in a quart, so 32oz in a quart. 4 quarts in a gallon. So, #4*32=128#. But, since she can only buy 1-gallon jugs, she would have to buy 2.
