It refers to the fact that the bottles were 1/5th of a gallon. These days most bottles are 750 ml, which is close to 1/5 of a gallon. A gallon contains 128 fluid ounces. So a fifth (1/5) or 750ml contains a tad more than 25 oz, or 25 one-ounce shots. Of course, many use 1 Â½ ounce for a standard shot which is around 16 shots. Bar Measurement Chart.
For the old folk, this is all very Imperial, no room for ml or answers like 17.07! A 'fifth' meant a fifth of a gallon. An Imperial gallon is 160 fluid ounces, so a 'fifth' is 32 fl oz.

In America a gallon of spirits has shrunk and there are only 128 US fl oz to the, different again, US gallon. See http://en.wikipedia.org/wiki/Flu....
