Question 44

15.989

When adding the numbers 3.7, 7.289, and 4, the result is 15.989, which accounts for all decimal places in the original numbers.

A) 15.989

This option is correct as it accurately represents the sum of the numbers when calculated. The addition of 3.7 (which can be expressed as 3.700), 7.289, and 4 (which can be expressed as 4.000) results in 15.989, maintaining the necessary decimal precision.

B) 5.226

This option is incorrect because it does not represent the sum of the numbers provided. The addition of the three values far exceeds 5.226, indicating a misunderstanding of the basic arithmetic involved.

C) 15

This option is incorrect as it fails to include the decimal places of the numbers being added. The correct sum of 15.989 clearly demonstrates that the whole number is not sufficient to represent the full result.

D) 15.07

This option is also incorrect because it misrepresents the total sum of the values. The proper arithmetic shows that the correct total is significantly higher than 15.07.

Conclusion

The correct answer, 15.989, reflects the accurate sum of the three numbers, including all necessary decimal places. The other options either underestimate the total or disregard the required precision, confirming that they do not meet the criteria set by the question.
