Understanding Rounding
Rounding is a method used to reduce the number of decimal places in a number while keeping its value close to the original. When rounding to a specific number of decimal places, we look at the digit immediately after the last decimal place we want to keep.
Steps to Round "3.8439" to 2 Decimal Places
- Identify the number: The number we want to round is 3.8439.
- Determine the target decimal places: We want to round this number to 2 decimal places.
- Locate the relevant digits:
- The digits after the decimal are 8 (1st), 4 (2nd), 3 (3rd), and 9 (4th).
- We will keep 8 and 4 for 2 decimal places and look at the next digit, which is 3.
- Apply the rounding rule:
- If the digit after the last decimal place we are keeping (which is 3 in this case) is less than 5, we do not change the last kept digit.
- Since 3 is less than 5, we keep the 4 as is.
Final Result
- The rounded number is 3.84.
- Therefore, the correct option is a) 3.84.
Conclusion
Rounding helps simplify numbers for easier interpretation and calculation. In this case, rounding "3.8439" to two decimal places results in 3.84.
