Mixed Number vs. Improper Fraction
  • A mixed number has a whole number part and a
    fraction part.
  • An improper fraction has a numerator that is
    greater than its denominator.

    make a mixed number an improper fraction.
  • Heres how you do it
  • First, breathe!!

2 4 8
Next, you add the numerator to what you just
multiplied.
8 3 11
Last, you put that new number over the same
denominator from the mixed number

9
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.
  • Example

  • 3
