First, you need to find what the fraction is for 4 cups of water. Make the denominators equal(so you can subtract.) Do you know how to do that?

\[{4\over6}-{3\over6}={1 \over 6}= 4 cups\]

It's protocol to explain first.

Now we know that 1/6 is 4 cups, we want to find 6/6 (which is 6 parts.) So, to get your answer, you multiply 4 by 6.
