20%

To solve this problem, you need to set up an equation. The equation you would set up is 40 x n=8. What you are trying to find is what n is as a percent. So to find the decimal version of n, you divide both sides by 40, which gives you n=.2. Then multiply this by 100 to make it a percent. So you get 20%.
