The smallest natural number which on rounding off to the nearest hundreds will give 400 is:
399
401
499
350
The numbers which on rounding off to the nearest hundred give 400 are: 350,351,352,…………………,448,449
The smallest number out of these is 350
Therefore, option D is correct answer.
Find the smallest and greatest numbers which are rounded off to the nearest hundreds as 900.
Give a rough estimate (by rounding off to nearest hundreds) and also a closer estimate (by rounding off to nearest tens): 108734-47599
Rounding off 2784 to nearest hundred will give us ____.
Rounding off each number to the nearest tens before performing the required operation gives more accurate estimate than rounding off each number to the nearest hundreds or thousands.
