Answer:

25 730 to nearest thousand
Agata [3.3K]
If you round 25,730 to the nearest thousand, you should look at the digit directly before the thousands digit, which, in this case, is 7. In mathematics, if the digit is equal to or greater than 5, you should round upwards. Since 7 is greater than 5, the answer to this problem is 26,000. 
Hope this helped!
