chapter 3 Decimals

We now use what we learned in Chapter 1 to develop rules for arithmetic with

decimal numbers. Although calculators can do the arithmetic for you, you

might find yourself without a calculator or in a class that does not permit cal-

culators. Some of what we cover in this chapter will help us later when we

solve equations and word problems.

CHAPTER OBJECTIVES

In this chapter, you will

• Write a decimal number as a fraction


• Perform arithmetic with decimal numbers


• Simplify fractions containing decimal numbers


• Rewrite division problems containing decimal numbers
