Amuseum has 275,608 visitors last year. what is this number rounded to the nearest thousand, and how do you know?

If you want to round to the nearest thousand, find the thousands place then look to its neighbor to the right, the hundreds place. If the hundreds place is 5 or more, the thousands place goes up by 1. If it is 4 or less, it stays the same. In this case the hundreds place is a 6 so the thousands place goes up 1 and everything to the right becomes a zero.

276,0000
