            Like Fractions


                                4                           6                           7

                                8                           8                           8


            From the above it is clear that

                    4       6       7
                        <       <
                    8       8       8

            We compare the numerators. The greater numerator is a greater fraction.

                                                    7
            Example   :  Compare      and      .
                                          8         8
                                          4          7
            Solution    :  Fractions          and        are  like  fractions.  The  denominators  of  these
                                          8          8
                             fractions are the same. On comparing the numerators, we find 4 < 7.

                                       4     7
                             Hence,      <     .
                                       8     8

                                           3         1
            Example   :  Compare       and      .
                                           4         2
                                            1
            Solution    :  Converting      to a like fraction we get
                                            2
                              1     1 × 2       2
                                =           =
                              2     2 × 2       4

                             Now, the given fractions are like fractions, as the denominators are the
                             same. On comparing the numerators, we find 3 > 2.

                                           3     2      3     1
                             Therefore,      >     or      >            (Writing the original fraction).

            Example   :  Arrange these fractions in ascending order.

            Solution    :
                             24 24 24 24 24
                             The ascending order is
                                                                    4       5      6       9     14
