12.  Write the expanded form of the given numbers.


                           (a) 792 =              +        +              (b) 864 =             +         +



                           (c) 247 =              +        +              (d) 395 =             +         +



                           (e) 618 =              +        +              (f) 503 =             +         +



                     13.  Write the short form of the given numbers.


                           (a)  400 + 10 + 9 =                            (b)  200 + 20 + 2 =




                           (c)  900 + 80 + 9 =                            (d)  600 + 50 + 4 =



                           (e)  500 + 90 + 0 =                            (f)  800 + 70 + 3 =



                     14.  Fill in the blank boxes.


                           (a)    3    hundreds +       4    tens +    1    one  =    300    +   40   +   1   =



                           (b)    6    hundreds +       2    tens +    5    ones =           +       +        =




                           (c)         hundreds +            tens +         ones =           +       +        =   438



                           (d)         hundreds +            tens +         ones =    200    +   90   +   7   =


                    Comparing Numbers



                    Let’s revise the rules we follow to compare 3-digit numbers.

                     •  First compare the digits in the hundreds place.

                                876, 765                    Since 8 > 7, so 876 > 765.


                     •  If the digits in the hundreds place is the same, compare the digits in the
                          tens place.

                                476, 495                    Since 7 < 9, so 476 < 495.
