2. A rational number can be written as a fraction (where denominator is not 0) Exs:,, Rational Numbers Chapter 1: Rational Numbers & Percents

3. Rational Numbers Include: Chapter 1: Rational Numbers & Percents  Whole numbers – zero and counting #s  Integers – whole #s and their opposites  Fractions, Mixed Numbers, Percents  Decimals:  Terminating – division ends with remainder of zero  Repeating – pattern of digits continues infinitely

4. Equivalent Fractions Chapter 1: Rational Numbers & Percents  Negative rational #s can be rewritten in 3 ways: Ex:  For every rational #, there are an infinite number of equivalent fractions…just multiply the numerator and denominator by the same factor! Ex:

5. Fraction  Decimal Chapter 1: Rational Numbers & Percents Write it the way you read it! Ex: is read, “negative one and five eighths”  identify whole #  “and” is decimal point  use calculator to solve 5÷8=0.625 So…-1.625

6. Decimal  Fraction Chapter 1: Rational Numbers & Percents Write it the way you read it! Ex: 0.45 is read “forty-five hundredths”  Read using place value to identify denominator  Simplify fraction So…
