Understanding Rounding Off
Rounding off is a mathematical technique used to simplify numbers while retaining their approximate value. When we round a number to the nearest ten, we look at the digit in the units place (the last digit) to determine whether to round up or down.
Steps to Round 1234 to the Nearest Ten
1. Identify the Number: We are rounding the number 1234.
2. Locate the Units Digit: The units digit (last digit) of 1234 is 4.
3. Determine Rounding Rule:
- If the units digit is less than 5, we round down.
- If the units digit is 5 or more, we round up.
4. Apply the Rule:
- Since the units digit is 4 (which is less than 5), we will round down.
5. Find the Nearest Ten:
- Rounding down 1234 gives us 1230.
Conclusion
Thus, when rounding 1234 to the nearest ten, the correct answer is 1230. Therefore, the correct option is a) 1230.
Rounding helps in making calculations easier and provides a quicker way to estimate values, which is essential in everyday situations such as budgeting and measuring.
