                    Look at the following place value chart.

                        Periods             →              Thousands                               Ones

                        Places              →    Ten Thousands  Thousands            Hundreds        Tens       Ones
                                                       (TTh)             (Th)           (H)           (T)        (O)
                        Value of places →             10000             1000            100           10           1

                    The ones period has three places – Ones, Tens and Hundreds.
                    The thousands period has two places – Thousands and Ten Thousands.

                    Let us write 51648 in the place value chart and see how it helps in us read the number.

                                        Thousands                                               Ones

                          Ten Thousands                Thousands              Hundreds             Tens           Ones
                                (TTh)                      (Th)                  (H)                (T)            (O)

                                  5                          1                    6                  4              8

                    All the  digits  in the  same  period  are read together  along with the  period’s  name,
                    except ones. Using commas makes it easy to read and write bigger numbers.

                    Thus, 51,648 is read as fifty-one thousand six hundred forty-eight.

                    Let us have a look at some more 5-digit numbers.

                      Numbers                              read as

                       10,005       Ten thousand five

                       20,409       Twenty thousand four hundred nine                                     Tips

                                                                                                The period is not written
                       45,499       Forty-five thousand four hundred ninety-nine                in plural while writing the

                       67,368       Sixty-seven thousand three hundred sixty-eight              number name.
                       99,999       Ninety-nine thousand nine hundred ninety-nine

                    99,999 is the greatest 5-digit number.

                    example 1. Write the number for ‘Twenty-three thousand four hundred sixteen’ in figures.

                    Solution. Twenty-three thousand four hundred sixteen can be written as:

                                                                                                                  9
