Does 648 round down or round up to the nearest hundred?

Answer 1

648 rounds up to the nearest hundred. When rounding to the nearest hundred, you look at the digit in the tens place, which is 4 in this case. Since 4 is less than 5, the hundreds digit remains the same and the tens and ones digits become zero. Therefore, 648 rounds up to 700.

Answer 2

To round to the nearest hundred, look at the tens digit - if it is 4 or less, round down otherwise it is 5 or more and so round up:

In 648, the tens digit is 4 (which is 4 or less) so round down to 600.
