                  example 1: Mohit has 14 roses. 3 of them are red. What is the
                  fraction representing:

                       (a)  red roses out of the total roses?          (b)  not red roses out of the total roses?

                  Solution:  (a) Total number of roses = 14      (b) Number of roses, which are not red
                                       Number of red roses = 3               = 14 – 3 = 11

                                       Fraction representing red             Fraction representing not red roses

                                                                                                     1
                  example 2: Neena had 24 chocolates. She ate half of them and gave   to her sister.
                                                                                                     4
                       (a)  How many chocolates did she eat?
                       (b)  How many chocolates did she give to her sister?

                  Solution:      (a) Total chocolates = 24                  (b) Number of chocolates she gave =

                                                                               1
                                  Number of chocolates she ate                 of total chocolates
                                  = Half of total chocolates                   4  1
                                       1                                     =   of 24 (or 24 ÷ 4)
                                  =   of 24 (or 24 ÷ 2)                          4
                                       2                                     = 6 chocolates
                                  = 12 chocolates                           Thus, she gave 6 chocolates to her

                                 Thus, Neena ate 12 chocolates.
                                                                            sister.
