Improper Fraction to a Mixed Number

• To turn an improper fraction to a mixed number,
  you
• Simply divide the denominator by the numerator.
  This will give you a whole number.
• Then, you subtract the numerator by having you
  have left over from the division.
• Last, put this fraction over the same denominator
  in the improper fraction.

• An improper fraction is a fraction where the
  numerator is larger than the denominator.
