              addition and suBtraction oF Fractions
              addition and subtraction of like Fractions

              To add  or subtract  like fractions,  add  the  numerators of both  fractions  and  keep the
              denominator same.

                                      3
              example 1:  (a) add   and       2                 (b) subtract   4   from   11 .

                                                       5
              Solution:     (a)   3  +   =   3 + 2  =                                     =  5

                            (b)   11  –   4   =  11 – 4  =   7                        11  –   4   =   7

              example 2:  Renuka read   pages of a story-book in the morning and   pages
                                            8                                                  8
              in the evening. How many pages in all did Renuka read in that day?
                                            5
                                                    1
              Solution:     The fractions   and   are like fractions.
                                            8       8
                                 5
                                      1
                                                    6
                            So,  +   =     5 + 1  =   =   3
                                 8    8      8      8    4                                             5       1
                                                   3
                            Thus, Renuka read   of the pages in that day.                              8       8
                                                   4                                                  6  =  3

                                                                                                          4
