Whats 307 495 rounded to the nearest thousand

You are rounding to thousands. To do that, you need to examine the digit in the place to the right of the thousands place, which is the hundreds place. The hundreds digit in this number is 4. It is not 5 or greater, so we have no need to increase the thousands digit. All we need to do is replace all digits to the right of the thousands digit by 0.

... ≈ 307,000

The answer should be 308 000
