You can do this a couple of ways:

Find a ratio of the volume and that will be a decimal.  Multiply by
100 to change to percent.

Ratio of small to large is:

3/5 = 36/60 = .60

Solve a ratio and proportion as follows:

100    60
--- = ----
250    x

Or you can also just multiply .60 times 250 to get your answer for x.
