Jawaban:

To round 450 to the nearest hundred, you would look at the number that is halfway between the two nearest hundred numbers, which in this case would be 400 and 500. If the number you are rounding (450) is greater than or equal to this halfway number (450 is equal to 450), you would round up to the nearest hundred, which would be 500. If the number you are rounding is less than the halfway number, you would round down to the nearest hundred, which would be 400. Therefore, 450 rounded to the nearest hundred is 500.
