Round 484 to the nearest ten and to the nearest hundred. Between what two multiples of 100 is 484?
The correct answer and explanation is:
To round 484 to the nearest ten, look at the digit in the ones place, which is 4. According to rounding rules, if the ones digit is 5 or greater, round up, and if it’s less than 5, round down. Since the ones digit is 4, which is less than 5, you round down. Therefore, 484 rounded to the nearest ten is 480.
To round 484 to the nearest hundred, look at the digit in the tens place, which is 8. Since 8 is 5 or greater, you round up. Therefore, 484 rounded to the nearest hundred is 500.
Now, to find the two multiples of 100 between which 484 lies, first note that the closest multiples of 100 are 400 and 500. Since 484 is closer to 500 than to 400, it lies between 400 and 500.
In summary:
- 484 rounded to the nearest ten is 480.
- 484 rounded to the nearest hundred is 500.
- 484 lies between the multiples of 400 and 500.
