Question

How to estimate from nearest tens , hundreds and thousands

Answer 1

In order to estimate to nearest thousands we follow the following procedure:

Step I: Obtain the number.

Step II: Examine the digit at hundreds place.

Step III: If the digit at hundreds place is less than 5, replace each one of the digits at hundreds, tens and ones or units place by 0 and keep all other digits as they are.  

If the digit at hundreds place is 5 or greater than 5, increase the digit at thousands place by 1 and replace each one of the digits at hundreds, tens and ones place by 0.

The number so obtained is the number rounded off to the nearest thousands.
