Introduction and Summary
Percents are used to calculate tax, tips, and even test grades. This chapter will teach the meaning of a percent, and how to convert between fractions, decimals, and percents. It will also explain how to calculate percents; that is, how to find the percent of a number.
This chapter is broken down into two sections. The first section will explain what the term "percent" means. It will also explain how to convert percents to decimals, and vice versa, as well as how to convert percents to fractions, and vice versa. These are the same conversions teachers use to figure out their students' test scores.
The second section will focus on how to find the percent of a number. In addition to its usefulness in mathematics, many other fields require this skill--economics, chemistry, statistics, and psychology, to name a few. This skill is also useful in everyday life; one is often asked to calculate a tip or to figure out how much tax will be added to an item.
