              example 4:  Round off 4962 to the nearest hundreds.

              Solution:       th    H     t    O          th    H    t     O

                                      4962     5000
                             4962 rounded off to the nearest hundreds is 5000.


                       Quick Check
                     Select the correct round off to the nearest 100 for the following facts.

                    1. The height of Mount Everest is 8,848 m.           8,900 m        or 8800 m

                    2. The length of the river Ganges is 2,525 km. 2,500 km             or 2,530 km
                    3. The diameter of the Earth is 12,742 km.           12,700 km      or 12,740 km
                    4. The light travels 2,99,792 km in one              2,99,790 km or 2,99,800 km
                       second.


              rounding off to the nearest thousands

              When we round off a number to the nearest thousands, we look for the digit at the
              hundreds place.

                  Š If the digit at the hundreds place is less than 5, keep the thousands place digit as
                  it is and replace the hundreds, tens and ones places digits with 0.

                  Š If the digit at the hundreds place is 5 or greater than 5, increase the thousands
                  place digit by 1 and replace the hundreds, tens and ones places digits with 0.

              example 5:  Round off 24382 to the nearest thousands.

              Solution:       tth th H t O                 tth th H t O                   Nearer to 24000 than 25000

                                         3 < 5
                                    24382      24000
                             24382 rounded off to the nearest thousands is 24000.
              example 6:  Round off 96704 to the nearest thousands.

              Solution:       tth th H t O                 tth th H t O                 Nearer to 97000 than 96000

                                                                                     96000             96704    97000
                                         7 > 5
                                    96704      97000
                             96704 rounded off to the nearest thousands is 97000.
