TYPES OF FRACTION

Fraction

As we all know that, in any fraction such as X / Y, the dividend ‘X’ is considered as “Numerator” and ‘Y’ is considered as “Denominator” and as an example, if 5/8 is a fraction then 5 is a “Numerator” and 8 is a “Denominator”.

On the other way, if I cut fruit into 6 pieces and I have taken 1 piece from 6 pieces, then it can be written as I have taken 1/6 of the whole part of the fruit.

There are some type of fraction are discussed and mention below –

a) Common Fraction

The numerator and denominator are integers in a common fraction

   4           7           11

-------, --------, --------  are common Or simple fraction.

   15         25          70

 

b) Complex Fraction

If in a fraction, either denominator or numerator or both the denominator and numerator contains fraction is called complex fraction –

   2/3         7/11        13

--------, --------, --------   are some complex fraction

   5/7          15        9/17

 

c) Proper Fraction

If in any fraction, the numerator is less than denominator then the fraction is called a proper fraction

    2          5          11

-------, -------, --------  are some proper fraction

    7         12         25

 

 

d) Improper Fraction

If in any fraction, the numerator is greater than denominator then the fraction is called an improper fraction

   11         21         47

-------, -------, --------  are some improper fraction.

    8         12         31

 

e) Mixed Fraction -

If in any fraction, an integer together with a proper fraction is called a mixed fraction.

     5            7            3

1 ------ , 3 ------ , 2 -------  are called mixed fraction

     7            11           5


Mix Fraction can be converted into an improper fraction as follows –

                    Integral Part X Denominator of the Proper Fraction +                              Numerator of the Proper fraction

Mixed Fraction = ----------------------------------------------

                                                                                                                           Denominator

 

 

       5           1 X 7 + 5           12  

 1 ------- = -------------- = -------

       7               7                 7

 

 

      7          3 X 11 + 7            40

 3 ------ = --------------  = --------

      11             11                 11

 

 

      3           2 X 5 + 3         13

2 ------- = ------------- = -------

      5               5                5

                                                                                                                                                    Reminder

Mixed Fraction= Quotient in (Numerator/Denominator) + ---------------

                                                                 Denominator

                                                                                                                                                               

If, there are quotient = 4, Reminder =  3,  Denominator = 5,

                                3

then Mix Fraction =  4 + -------

                                5

                                                                                                               3

      Mix Fraction = 4 -------

                             5
