    Example 4. Compare:
                                 a.  9728 and 9706                            b.  6543 and 6598

                    Solution.  a.  Th H         T O                           b.    Th H     T O
                                       9   7    2   8                               6    5   4    3

                                       9   7   0 6                                  6    5   9    8

                                      Same           20 > 0                         Same           40 < 90

                                     So, 9728 > 9706.                             So, 6543 < 6598.
                       If all other digits except the ones are the same, then compare the ones digits.

                    The number with the greater digit in the ones place is greater.

                    Example 5. Compare:

                                 a.  8732 and 8734                            b.  5498 and 5494

                    Solution.  a.   b.         T O                            b.   Th H      T O
                                      Th H
                                      8    7   3    2                               5    4   9    8

                                      8    7   3    4                               5    4   9    4

                                        Same             2 < 4                       Same              8 > 4

                                     So, 8732 < 8734.                             So, 5498 > 5494.

                    Example 1. Find the greatest number in the following group.

                                          2648           369           2658

                    Solution.

                    Step 1.  Write the numbers in the place value chart.                          Th H      T O
                    Step 2.  Remove the smallest number from the group.                            2    6   4    8
                              Here, 369 is the smallest number.                                         3   6   9

                                          2648           369           2658                        2    6   5    8

                    Step 3.  Remove the smaller number from the remaining
                              numbers.                                                            Th H      T O

                              Here, 2648 < 2658.                                                   2   6    4   8

                                          2648          2658                                       2   6    5   8

                    Step 4.  2658 is the largest number in the group.                             Same           40 < 50

                                                                                                                  21
                                                                                                     Numbers
