How do you round 657000 to nearest ten thousands?

Answer 1

First find the ten thousands place. In this case it is the digit 5 in the number.
Now considered the place below it or the thousands place.
If the thousands place value is 5 or greater, round up.
Since 7 is greater than 5, we know to round up:
657000 rounds to 68000

Another answer:657000 is only 3000 less than 660000 but it is 7000 more than 650000 so the nearest 10 thousand is 660000.

The top explanation does give the same answer as the second one - following the reasoning does give 657000 rounding to 660000 to the nearest ten thousand
