Question 3

The sum of the numbers is 14.989.

To find the sum of 3.7, 7.289, and 4, we add these values together, yielding a total of 14.989 when all decimal places are reported.

A) 14.989

This option is correct as it accurately represents the sum of 3.7, 7.289, and 4, which calculates to 14.989 when all decimal places are included.

B) 5.226

This option is incorrect because it does not reflect the correct sum of the given numbers. The numbers being added are significantly larger than 5.226, making this value not a plausible result.

C) 15

This option is also incorrect. While 15 is close to the actual sum, it does not account for the precise decimal values from the addition, thus failing to represent the total accurately.

D) 15.07

This option is incorrect as well. Although it is a number greater than 15, it does not accurately calculate the sum of the provided numbers, which is specifically 14.989.

Conclusion

The correct answer, 14.989, represents the accurate sum of the numbers when all decimal places are considered, while options B, C, and D fail to provide the correct total. This highlights the importance of precise arithmetic in achieving the correct result.
