What is the sum of 9.98 and 0.065?

Rationale

9.98 plus 0.065 equals 10.045.

To find the correct sum, we add the two numbers together, which results in 10.045. This value is derived from precise addition of decimal numbers, ensuring that each place value is correctly aligned.

A (10.63) YOUR ANSWER

This choice incorrectly suggests a sum that is significantly higher than the actual result. The addition of 9.98 and 0.065 does not reach 10.63, as it overshoots the true total by a margin of 0.585.

B (10.045) CORRECT

This choice correctly reflects the sum of 9.98 and 0.065. By aligning the decimal points and adding, we confirm that 9.98 + 0.065 equals 10.045, making this the correct answer.

C (1.0063) YOUR ANSWER

This option represents a sum that is far too low and does not logically follow from the numbers provided. The addition of 9.98 and 0.065 should result in a value greater than 10, making 1.0063 an invalid outcome.

D (998.065) YOUR ANSWER

This choice indicates a sum that is excessively high, as it erroneously suggests that the total exceeds 1000. Such a result is impossible given the original numbers, which are both less than 10.

Conclusion

To summarize, the sum of 9.98 and 0.065 accurately computes to 10.045, validating choice B as the correct answer. The other options present results that either significantly underestimate or overestimate the true sum, demonstrating the importance of careful decimal addition in achieving accurate calculations.
