This is really easy if you think and look at the picture.

There were 15 dvds. 1/5 were documentaries.

All you have to do is figure out what 1/5 of 15 is. Yes?

So to find out what 1/5 of 15 is, you divide 15 by 5, and that's your answer.

The answer is 3.
The answer is three, to check: count to five, and point at each dot. Every time you say 5, put a little pencil dot on the blue circle. When you found the pencil dots, you could end up with three.
