What percentage of body fat do you need to see abs?

I would say don't worry about that... Ab's don't appear unless your belly fat is limited :P anyways running REALLY helps you lose belly fat!! than do 1 minutes of sit ups every day for a week, the next week do sit ups for 2 minutes straight, then the next week you should do sit ups for 3 minutes everyday for a week. , after this start doing more different Ab exercises like V- sits
