Pictorial Representation of Fraction




     1
     4          One fourth is yellow
Example 1
   We divide a chocolate bar into 5 equal parts.




                                  Each part is 1/5 of the whole
                                   bar.

                                  We read 1/5 as one fifth.
                                   The whole bar has 5 fifth
                                   parts.

                                  We write it: 1 = 5/5
Example 2
   We have a box of gingerbread men. There
    are 5 men in the box.
    Each man is 1/5 of the box contents.


                        The whole box has 5 fifth parts.
                        We write it: 1 =
                        Two gingerbread men are pink.
                        Two pink men are    of the box contents
