                  If all other digits except ones are the same, then compare the ones digits. The number
                  with a greater digit at the ones place is greater.

                  example 5: Compare: (a) 9,115 and 9,118                   (b) 3,229 and 3,224

                  Solution:        th H      t   O                               th H      t    O

                                    9   1    1   5                                3    2   2    9
                                    9   1    1   8                                3    2   2    4

                                     Same              5 < 8                         Same              9 > 4
                                 So, 9,115 < 9,118                                So, 3,229 > 3,224

                  greatest aND smallest Numbers

                  Let us find the greatest number among 7,839; 999 and 5,326.                            th H      t   O
                  Step 1: Arrange the numbers in the place value chart.                                   7    8   3    9
                                                                                                                        9
                                                                                                                   9
                                                                                                               9
                  Step 2: Cross the smallest number (999) from the group.                                 5    3   2    6
                                                     7,839          999          5,326
                  Step 3: Out of the remaining two numbers, compare which is the greater number. In this

                           case, 7,839 is greater than 5,326.
                  Step 4: Thus, 7839 is the greatest number among 7,839; 999 and 5,326.

                  example 1: Find the greatest number among 4,562; 1,234 and 2,076.

                  Solution:  Step 1: Arrange the numbers in the place value chart.                       th H      t   O
                               Step 2: Cross the smallest number (1,234) from the group.                  4    5   6    2

                                          4,562          1,234         2,076                              1    2   3    4

                               Step 3:  Out of the remaining two numbers, compare which                   2    0   7    6
                                          is the greater number. In this case, 4,562 is greater than 2,076.

                               Step 4: Thus, 4,562 is the greatest number among 4,562; 1,234 and 2,076.

                  example 2: Find the smallest number among 4,215; 6,738 and 9,831.
                  Solution:  Step 1: Arrange the numbers in the place value chart.

                               Step 2: Cross the greatest number (9831) from the group.                  th H      t   O
                                                                                                          4    2   1    5
                                           4,215         6,738         9,831                              6    7   3    8
                               Step 3:  Out of the remaining two numbers, compare which                   9    8   3    1

                                          is the greater number. In this case, 6,738 is greater than 4,215 or you
                                          may say 4,215 is smaller than 6,738.

                               Step 4: Thus, 4,215 is the smallest number among 4,215; 6,738 and 9,831.
