Understanding Rounding to the Nearest Hundreds
Rounding to the nearest hundreds involves adjusting a given number to the closest multiple of one hundred. This skill is crucial in various real-life applications, from budgeting and financial planning to estimating quantities in science and engineering.
Basic Rules of Rounding
To effectively round a number to the nearest hundred, students should follow these simple steps:
1. Identify the digit in the hundreds place: This is the third digit from the right in a whole number.
2. Look at the digit to the immediate right (the tens place):
- If this digit is 5 or greater, round up.
- If this digit is less than 5, round down.
3. Adjust the hundreds digit accordingly: If rounding up, increase the hundreds digit by one; if rounding down, keep it the same.
4. Replace all digits to the right of the hundreds place with zeros.
For example:
- Rounding 356:
- The hundreds digit is 3, and the tens digit is 5.
- Since 5 is equal to or greater than 5, we round up.
- The result is 400.
- Rounding 242:
- The hundreds digit is 2, and the tens digit is 4.
- Since 4 is less than 5, we round down.
- The result is 200.
