          1. Subtract  the  following  fractions  and  show  the  difference  by  shading  the  appropriate
              number of parts of the given figures. One has been done for you.


              (a)   5  −  3   =   2              (b)  5  −  2   =                 (c)  3  −  2   =

                                     2
        Example 1:   Priya read   of her book in the morning and             3   in the evening. What part of the

                       book has she read?

        Solution:      Fraction of book read in the morning =        2
                                                                     7
