25,386 round the number to the nearest thousand

First, the place value "thousand" is where the '5' is in 25,386.
Now, look at the numbers following the five. 386 does not round up to 1000 but rounds down to 0 instead since it is not 500 or more.
So, 25,386 to the nearest thousand place is 25,000.

Hope this helped! :)
