Question

572 to the nearest hundred

Answer 1

72 is 50 or above so you round it up.
572 to the nearest hundred is 600

Answer 2

If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up (+1).


If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down (no change).

572 ≈ 600
