                  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

                  Step 2: Cross the smallest number (999) from the group.                                      9   9    9
                                                                                                          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.

                  orDeriNg oF Numbers

                  We arrange the numbers in increasing order, that is, from the smallest to the greatest; it is
                  called ascending order. Ritvik noted down the numbers from the number plates of four cars.
                  The numbers are 2,937, 6,543, 1,359 and 5,023.                                  th H t O

                  He wants to arrange the numbers in a particular order.                          2 9 3 7

                  First, he writes the given numbers in the place value chart and                 6 5 4 3         Greatest
                                                                                                  1 3 5 9
                                                                                                                  Smallest
                  then starts comparing.                                                          5 0 2 3
                  Looking at the thousands place digits, 2, 6, 1 and 5; he finds that 1 < 2 < 5 < 6.

                  Thus, the four numbers in ascending order will be arranged as:
                         1,359 < 2,937 <  5,023 < 6,543
