2
9-2 Extension: Negative Rational Numbers Learn to compare and order negative rational numbers.

3
9-2 Extension: Negative Rational Numbers A rational number is a number that can written as a ratio, with any integer as the numerator, and any integer except 0 as the denominator.

4
9-2 Extension: Negative Rational Numbers Additional Example 1A: Comparing Negative Rational Numbers Use, or = to compare each pair of numbers. A. Write the fractions using a common denominator. Compare.

5
9-2 Extension: Negative Rational Numbers Additional Example 1B: Comparing Negative Rational Numbers Use, or = to compare each pair of numbers. B. –0.5 –3 Line up the decimal points and compare from left to right. –0.5 –3.0 0 is greater than –3. –0.5 > –3

6
9-2 Extension: Negative Rational Numbers Additional Example 1C: Comparing Negative Rational Numbers Use, or = to compare each pair of numbers. C. Write –1/2 as a decimal. Compare. –0.5 < –0.3
