Question 4

1/2 of (6 + 3 + 9 + 7) is 12.5.

To find 1/2 of the sum of the numbers 6, 3, 9, and 7, first calculate the total: 6 + 3 + 9 + 7 = 25. Then, taking half of 25 results in 12.5.

A) 14

Option A is incorrect because it does not reflect the correct calculation of the sum. Half of 25 is not 14; rather, it is lower, thus this choice does not follow the arithmetic operations required.

B) 12.5

This option is correct as it accurately represents 1/2 of the total sum of 25. The calculation shows that taking half of 25 yields 12.5, confirming that this choice meets the requirements of the question.

C) 3.5

Option C is incorrect as it significantly underestimates the value derived from the calculation. 3.5 does not correspond to any logical division of the sum 25, failing to reflect the proper mathematical operation.

D) 11.5

This choice is incorrect because it also does not match with the proper calculation of 1/2 of the sum. 11.5 is not half of 25 and does not align with the expected outcome of this arithmetic operation.

Conclusion

The correct answer, 12.5, is derived from properly summing the numbers and dividing that sum by two. Other options fail to represent the correct calculation and do not fulfill the requirements of the problem, establishing 12.5 as the definitive answer.
