A number, containing no zeros, changed to 310,000 after it was rounded. To what place was the number rounded? Explain how you know. This is the question my 4th grader has on a homework assignment. I'm lost on the question and she states she doesn't know either and the teacher didn't go over it. Please help me to understand.
clearly the number was between
311,111 and 314,999
and was rounded to the nearest 10,000
It could not be less than 310,000, because then it would have been something like 306,827 with a zero.
