  • 13. Other Facts About Fractions
    Fractions are parts of a whole. They are not indicating how large the whole is.  Rather, they describe what part of the whole is represented.
    A fraction can be reduced if the numerator and denominator are evenly divisible by the same number. Divide both the numerator and denominator by the same number. The resulting numerator and denominator create the reduced fraction.
  • 14. The Difference Between a Proper and an Improper Fraction
    A proper fraction- the numerator is smaller than the denominator indicating a part of a whole.
