What would 672,831 be rounded to the nearest ten?

How you do it is, go to the tens place which is 3, now round it, you then go to the ones place, if the number is bigger than 4 then that would make the 3 a 4 and the ones place would just be a 0, if the ones place is less than 5 then the tens place would just be its normal number which is 3 and the ones place would be a 0 again, so the ones place is a 1 and that is less than 5, so the tens place would be the same, so then the answer would be 672,830!

672,830 is your answer
