Answer :
Answer: 9000
This is because the given value is closer to 9,000 than it is to 10,000.
The digit in the thousands place is 9. The digit to the right of this is 0, which is not 5 or greater. So we round down to the nearest thousand. So basically everything after the 9 is replaced with 0.
9000 would be the correct answer because it is closer to 9000 than it is 10,000
