CONVERSION FROM UNLIKE FRACTION INTO LIKE FRACTION

Conversion Of Unlike Fraction Into Like Fraction 


Step.1) We have to find the LCM of the Denominators of the Fraction

Step.2) Divide the LCM by the respective denominators

Step.3) Multiply the numerator and the denominator of each fraction by the corresponding quotient obtained in Step.2

                           5          7          11

Example.1)- Convert -------, -------, --------  into like fraction

                          12         36         18 

 

Answer) As per the given condition, first of all we have to find the LCM of the denominator

So, the required  LCM of the numerator of the given = 3 X 3 X 4 X 2 = 72

Now, we will find the factor via division of obtained LCM by denominator of given Fraction respectively, so we find –

72 ÷ 12 =  6 ,  72 ÷ 36 = 2 ,  72 ÷ 18 = 4

Now, we will multiply obtain factor to both numerator & denominator respectively and we find –

     5                5 X 6              30

---------  =  ------------  =  --------

    12               12 X 6             72                                                               

     7             7 X 2             14

--------- = ----------- =  ---------

    36            36 X 2             72

 

    11            11 X 4          44

--------  = ----------- = --------

    18            18 X 4          72

 

              30            14            44

Hence,  ---------,  ---------,  --------         (Ans.)

              72            72            72
