4-digit Numbers                                                                                         19

        Example 2:  Compare the numbers 4056 and 4213.

        Solution:          Both are 4-digit numbers. So, arrange them as per place value chart.

                          Th     H     T    O                   Th     H     T    O
                           4     0     5     6                    4    2     1     3


                                                     4 = 4


                                                     0 < 2                                 Thus, 4056 < 4213

        Example 3:  Compare 3250 and 3290.

        Solution:          Both are 4-digit numbers. So, arrange them as per place value chart.

                          Th     H     T    O                   Th     H     T    O
                           3     2     5     0                    3    2     9     0


                                                     3 = 3

                                                     2 = 2


                                                     5 < 9                                 Thus, 3250 < 3290



                                                   Exercise 2.5


          1. Fill in the blanks using >, < or =.

                (a)  1517          1527            (b)  2476          2760           (c)  2814           3157

               (d)  2425           2425            (e)  4056          4046            (f)  7275          7285

          2. Encircle the greater number.

                (a)  3564, 5364                    (b)  2651, 2561                   (c)  6991, 9691
               (d)  3296, 4265                     (e)  8449, 4928                    (f)  3543, 3554

          3. Encircle the smaller number.

                (a)  4067, 4576                    (b)  7129, 7219                   (c)  4567, 4576
               (d)  4032, 4320                     (e)  5129, 4298                    (f)  4201, 4202


        Ascending and Descending Orders

        When we arrange the numbers from the smallest to the greatest, the numbers are in
        ascending order.

        When we arrange the numbers from the greatest to the smallest, the numbers are in
        descending order.
        Let us arrange the given numbers in ascending and descending orders.
