      Working with Fractions and Decimals

      Fractions and decimals are closely related. A fraction can be expressed as either a repeating or terminating decimal. A decimal is a special type of fraction — it always has a denominator that’s some power of ten. Decimal numbers are often written with a lead zero. You’ll see 0.031 instead of .031. The lead zero helps keep the decimal point from getting overlooked.

The Problems You’ll Work On

      In this chapter, you’ll work with fractions and decimals in the following ways:

       Adding and subtracting fractions by finding a common denominator

       Multiplying and dividing fractions by changing to improper fractions and reducing where possible

       Simplifying complex fractions

       Adding and subtracting decimals by aligning decimal points

       Multiplying decimals by assigning the decimal place last

       Dividing decimals by assigning the decimal place first

       Changing fractions to decimals — repeating or terminating

       Changing decimals to fractions and then reducing
