       Identifying Fractions
Page 1
• Represent parts or pieces of a whole.
• Shows the operation of division.

              Numerator         5
              Denominator       8
*Draw a picture to represent this fraction.
        Equivalent Fractions
• Fractions that show the same amount
  with a different amount of pieces. (equal)
• A fraction you get when you multiply or
  divide the numerator and denominator by
  the same number.

8 = 4      5 = 20     7x 3 =       32 ÷ 8 =
24 12      9 36      15x 3         72 ÷ 8
                Simplest Form
• Showing the same amount by using the least number of
  pieces.

• Taking a fraction and dividing the numerator and the
  denominator by the same number (common factor) until
  you can’t divide anymore. Try finding the GCF to divide by!

                            12 ÷         =
                            64 ÷

*Draw a picture in your foldable book.
        Comparing Fractions
• When the denominators are the same, just
  compare the numerators.
• When the numerators are the same, compare the
  denominators-the larger the denominator, the
  smaller the fractional pieces.
• When the numerators and the denominators are
  different, find a common denominator by creating
  equivalent fractions.
4      4         7       14         9       6
5      9        36       36         12      8
        Ordering Fractions
• If the denominators are all the same, just
  compare the numerators and put them in
  order (least   greatest).

• If the numerators are the same, compare
  the denominators and then put them in
  order. (just like <, >, or =)

• If necessary, make them all equivalent
  fractions and then put the original
  fractions in order.
               Examples:
3    14    8   5   5    5   4    7   12
27   27   27   8   6   11   6   15   30
 Adding & Subtracting Fractions
• Add or subtract only the numerators in
  the fractions because you can’t change
  how many pieces they were originally
  divided into.

   2 + 5 =               36 - 18 =
   10 10                 72 72
  Identifying Mixed Numbers
• Represented by a whole number and a fraction
  together.
• When there is more than a fraction shown or
  a whole.
• In a division problem, the quotient represents
  the whole number, the remainder represents
  the numerator, and the divisor represents the
  denominator.


                             =1¾
  Adding & Subtracting Mixed Numbers
• Add or subtract the fractions first,
  regroup into the whole number column,
  if necessary.
• Then add or subtract the whole
  numbers.
                   2 5
         11              8   7
                    9    2   8
                +        8
                    11   7
                         8
       Improper Fractions
• When the numerator is larger than the
  denominator.
• Shows the a mixed number too!
                 7        pieces
                 4 total sections
    Converting Mixed Numbers &
        Improper Fractions
• Changing a mixed number           improper
  fraction. Magic “C”  +
                       1¾
                              x
 1 x 4 =4               4+3=7                  7
                                               4

 *Always put the answer over the same denominator!
    Converting Mixed Numbers &
        Improper Fractions
• Changing a improper fraction    mixed
  number .
   7 means 7 ÷ 4 = 1 R 3         1¾
   4
• The whole number in the quotient becomes
  the “whole” part of the mixed number.
  The remainder becomes the numerator and
  the denominator stays the same (divisor
  becomes the denominator).
