5
Parts of a fraction
  • There are two parts to a fraction
  • 5
  • 6
  • The top one is called the numerator. The
    numerator is the number that represents the
    amount that is shaded.
  • The bottom one is called the denominator. The
    denominator is the number that represents the
    amount of parts that the figure is divided into.

6
Types of fractions
  • There are three types of fractions
  • 1) proper fraction
  • A proper fraction by definition is one where the
    numerator is smaller than the denominator.
  • 3/4
  • 2) improper fraction
  • An improper fraction by definition is one where
    the numerator is bigger than the denominator.
  • 7/3
  • 3) mixed number.
  • 3) A mixed number by definition is one where
    there is a whole number and proper fraction.
  • 2 1 / 2

7
Changing from improper fraction to mixed number
  • Divide the denominator into the numerator. The
    quotient becomes the whole number, the remainder
    becomes the numerator and the denominator remains
    the same.
  • 5/4

8
Changing from mixed number to improper fraction
Multiply the denominator with the whole number
and add the numerator. Then place your answer
over the denominator.
6 ¼ 4 x 6 1 25/4
9
Equivalent Fractions
Two fractions are equivalent when they have the
same value. In order to see if they have the
same value divide both the numerator and the
denominator by the same number. In the case
below both the numerator and the denominator were
divided by 4. 4/8 1/2
