Question

Debbie needs to fill juice cup 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

1 Gallon = 128 onces

20 * 10 = 200 onces ( amount of liquid)

200 : 128 = 1.56 Gallon

so you need 2 bottles

the answer is not 1.56, because you can't buy a fraction of a bottle, so the answer is

2 bottles
