I remember reading somewhere that people, on average, understand integer ratios better than they understand percentages. As in you you write 283 out of 10,000 vs. 2.83% and then ask comprehension questions the former shows much better comprehension.

As a side note, I have personally encountered large number of adults who are unable to restate a percentage as a fraction, and even the idea that a percentage represents a fractional value is foreign to them.
