Question

Round-off the number $47,897$to nearest 1000.
A: $47,897$
B: $48,000$
C: $47,900$
D: $47,890$

Answer 1

Hint:
Whenever we see the problem on round-off to the nearest thousand, first we should focus on the hundredth position. If in the hundredth position the number is less than $5$ we need to round off the given number to its previous thousand, if the hundredth number is greater than or equal to $5$ then the given number should be round-off to the next thousand numbers.

Complete step by step solution:
In the given question they have asked to round-off the number to the nearest thousand.
So, for that first we need to see the number present in the hundredth position.
For your reference place values are shown as in the below diagram.

If the number present in the hundredth place is $1,2,3$ or $4$ then round off the given number to their previous thousand number.
For example: If a given number is $6,250$, in this case $2$is present at hundredth place so we need to round off the given number to the previous thousand number that is $6,000$.
If the number present in the hundredth place is $5,6,7,8$ or $9$ then we have to round off the given number to the next thousand numbers.
For example: $10,567$, here we have $5$ in the hundredth position so round off the given number to the next thousand that is $11,000$.
Now, we solve for given question that is $47,897$
Here, we have 8 in the hundredth position so we need to round up the number or increase the number at a thousand places.

Therefore the answer is $48,000$.

Note:
Sometimes the question may be like rounding off the number $499$ to the nearest thousand. Then you should not get confused because the answer will be 0, they may do that to confuse the students. If they ask for $500$ then the nearest thousand will be $1,000$.
