                                      Form the largest 6-digit number from all the number
                                      cards above. Then, round off the answer to the nearest
                                      ten thousand and the nearest hundred thousand.



                 4                                         The number on which card becomes

                            The numbers on cards S and R become 800 000 when
                            rounded off to the nearest hundred thousand.





                   1    Round off the following numbers to the nearest thousand,
                       ten thousand, and hundred thousand.

                   2    Round off:

                        a  RM259 648 to the nearest hundred thousand ringgit.
                        b  488 750 g to the nearest thousand gram.

                   3    State three numbers which become 600 000 when rounded off to


                       the nearest hundred thousand.
