        Proper Fraction                                                   I’m part of a whole, but not the whole.
        A fraction whose numerator is less than its                       I’m smaller in size,
        denominator is called a proper fraction.                          but I still have might,

        For example,       ,   ,    etc. all are proper fractions.        In between zero and one, I shine so bright.

        A fraction whose numerator is greater than or equal to the denominator, is called an improper
        fraction.

                        5 9
        For example,  ,,...
                        4 5

        A combination of a whole number and a proper fraction is called a mixed fraction.

        For example,          1 ,  3 , 2 ,...

        To express an Improper fraction as a Whole Number
        To  express  an improper fraction  as  a  whole  number, we  divide  the numerator  by  the
        denominator.

                                 16                                                                2
        Example:       Express        as a whole number.
                                  8                                                            8 16
                       We divide 16 by 8.                                                      – 16
                                                                                                   ×
                       16 ÷ 8 = 2
