Computing Price/Earnings Ratio is fairly simple, but understanding the concept is much more difficult. For struggling students you could modify the worksheet with easier numbers to compute, you can also allow them to use calculators. For advanced students you could have them look online and find some different P/E ratios and determine what companies they would buy if they had the money. You could also have students search for high and low P/E ratios online.

### Extensions
