Percentages are shown to be very similar to fractions. In fact they are exactly fractions whose denominator is 100. The chapter explains what percentages are, why we use them, and what we mean when we use them.

Step by step instructions are provided for how to calculate percentages when we need to compare values that are relative to very dissimilar bases. For example, is a score of 108 out of 150 better or worse than a score of 60 out of 80?
