Question

There are 4 cups in one quart and 4 quarts in a gallon. How man cups are there in 4 gallons of fruit punch? How many pints is this?

Answer 1

64 cups

32 pints

Explanation:

4cups=1qt, 4qts=1gal, 16qts=4gal

?cups=4gal

4•4qts=1gal•4=(4gal)

16qts=4gal

-so-

4cups=1qt, 4gal=16qts

16•4cups=1qt•16 (4gal)

64cups=4gal

----

4c=1q, 1q=2p, 4q=1g, 16q=4g, 64c=4g

4c=1q=2p, so 4c=2p, so 2c=1p (2:1)

64c(÷2)=?p

64c=32p

...but it's a trick question, if you don't know how many pints it takes to equal anything else. (ie. 1q=2p or 2c=1p)
