The sum of 9.98 and 0.065 is 10.045.

To find the sum of 9.98 and 0.065, you simply add the two numbers together, which results in 10.045.

A) 10.63

This option is incorrect because adding 9.98 and 0.065 does not yield 10.63. The correct computation shows that the sum is much less than this value.

B) 10.045

This option is correct as it accurately represents the sum of 9.98 and 0.065. When calculated, 9.98 + 0.065 equals 10.045, confirming this choice as the right answer.

This option is incorrect as it grossly overstates the sum. The addition of 9.98 and 0.065 results in a number that is far less than 998.065.

Conclusion

The correct answer, 10.045, is the only option that accurately reflects the sum of 9.98 and 0.065. All other options either significantly underestimate or overestimate the sum, confirming that they are not valid answers in this context.
