Answer 2

Answer:

Step-by-step explanation:

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.

For example:

Round off each of the following numbers to nearest thousands.

(i) 14329

Solution:

The given number is 14329.

Its digit at hundreds place is 3, which is less than 5. So, we replace each of the hundreds, tens and ones digits by 0 and keep the other digits as they are.

So, the number 14329 is rounded off to nearest thousands as 14000.

(ii) 14729

Solution:

The given number is 14729.

Its digit at hundreds place is 7, which is greater than 5. So, we increase the digit at thousands place by 1 and replace each one of the digits at hundreds, tens and ones place by 0 to get the rounded off numbers.

Hence, the number 14729 is rounded off to nearest thousands as 15000.

(iii) 14579

Solution:

The given number is 14579.

Its digit at hundreds place is 5. So, we increase the digit at thousands place by 1 and replace each one of the digits at hundreds, tens and ones place by 0 to get the rounded off numbers.

Hence, the number 14579 is rounded off to nearest thousands as 15000.
