Answer (1)
To solve the problem of rounding these numbers to the nearest hundred, we need to follow these steps for each number:
Identify the Hundreds Place:
For each number given, locate the digit in the hundreds place. For example, in the number 1,048, the hundreds digit is 0.
Look at the Digit to the Right:
Look at the digit immediately to the right of the hundreds place. For 1,048, this digit is 4 (which is in the tens place).
Determine Whether to Round Up or Down:
If the digit to the right of the hundreds place is 5 or greater, round up by adding 1 to the hundreds digit. If it is less than 5, do not change the hundreds digit.
For 1,048, since 4 is less than 5, we do not round up. Therefore, the hundreds digit remains 0, and the number rounds to 1,000.
Reconstruct the Number:
Replace the digits to the right of the hundreds place with zeros. With 1,048, this means it becomes 1,000 when rounded.
Apply the Same Method to Other Numbers:
Let's apply the rule to the remaining numbers:
8,980: The digit to the right of the hundreds place is 8. Since it's equal to or greater than 5, we round the hundreds digit up from 9 to 10. Therefore, 8,980 becomes 9,000 when rounded to the nearest hundred.
2,620: The digit to the right of the hundreds place is 2, which is less than 5. So, we do not change the hundreds digit 6, and the number becomes 2,600.
4,567: The digit to the right of the hundreds place is 6. Since it is greater than 5, we round the hundreds digit up from 5 to 6. Therefore, 4,567 becomes 4,600.
By following these steps, rounding numbers to the nearest hundred becomes a systematic process. Remember, the key is always the digit right next to the hundreds place that determines how we round the number.
