Title: Compare Fractions


1
Compare Fractions
  • SWBAT compare fractions with like denominators
    and fractions with unlike denominators

2
Think Share with a partner
  • What steps would you take if I asked you to
    compare (tell me which one is bigger) the
    following fractions?
  • 7/8 or ¾
  • Least Common Denominator (LCD)
  • The LCM of the two denominators

3
Comparing Fractions
  • If they have the same denominator (same size
    pieces) compare the numerators.
  • If they have different denominators, find the
    LCD, and rename the fractions
  • Then compare the numerators.

Examples
  • 7/8 and 5/8
