Rounding Numbers to the Nearest Hundred

Rounding Numbers to the Nearest Hundred

When you are rounding to the nearest hundred, look at the
tens place digit of the number.

If the tens place digit is 0, 1, 2, 3, or 4, then the hundreds digit
does not change. You are rounding down.

If the tens place digit is 5, 6, 7, 8, or 9, then the hundreds digit
increases by one. You are rounding up.

All the other digits after the hundreds digit (tens and ones digit) go to zero in both cases.

Example-1: Round 652 to the nearest hundred.
