                       SUB TOPIC-7: ADDITION AND SUBTRACTION OF LIKE FRACTIONS

               Addition of Like Fractions:

               In order to add two or more like fractions, we may follow the following steps:

               Step I:

               Obtain the fractions.

               Step II:

               Add the numerators of all fractions.

               Step III:

               Retain the common denominator of all fractions.

               Step IV:

               Write the fraction as Result in Step II / Result in Step III.


               For Example:

               Add the following fractions.

                  1
                       4
               1.  / 6 +  / 6

               Solution:

               We have,

               1 / 6 +  / 6
                    4

               =  (1+4) / 6
                 5
               =  / 6

                            4
                  2
                       3
               2.  / 7 +  / 7 +  / 7
