Question

Bob has a coupon for 1 free container of chocolate milk. He can either buy a 4.25 pint bottle, a 2.5 quart bottle, or a 0.5 gallon bottle. which should he choose if he wants the most chocolate milk?

Answer 1

2.5 quarts

1) We need to convert those measures to one unit so that we can compare then

4.25-pint bottle

2.5-quart bottle

0.5 gallon

2) We can set a proportion for that. Let's convert them into gallons

1 pint -------------------------0.125 gallons

4.25 pint--------------------- x

Cross multiplying it we get to:

x= 4.25 * 0.125 = 0.53 gallons

1 quart -----------------------------0.25g

2.5 quart ------------------------- y

y= 0.625 gallons

And the last one since it's in gallons, we don't need to convert.

3) Hence, the best option for Bob is picking a 2.5-quart bottle to get the most chocolate milk, since 0.5 gallons < 4.25 pint <2.5 quarts
