Ms. Witt and her family traveled all over the country this summer on vacation. She traveled 1,995 miles. When she was told to round to the nearest TENS place she said her estimated distance is 2,000. Did she do this problem correctly? Why or why not?
Yes, because if you round to the nearest tens place, the digit "9" becomes "10." Since each place only holds one digit, then you have to put a "0" in the tens and add the "1" to the hundreds. That changes the "9" in the hundreds to "10". Then you have to put a "0" in the hundreds place and add a 1 to the thousands place. It becomes 2,000.
