Question 12

1/2

Subtracting 3/12 from 9/12 results in 6/12, which simplifies to 1/2. Therefore, the answer to the subtraction problem is 1/2.

A) 1/3

The option 1/3 is incorrect because it does not accurately represent the result of the subtraction. When 3/12 is subtracted from 9/12, the result is 6/12, which simplifies to 1/2, not 1/3.

B) 1/2

This option is correct as it reflects the accurate outcome of the operation. When 9/12 - 3/12 is calculated, it equals 6/12, which simplifies to 1/2, confirming this choice as the correct answer.

C) 1/4

1/4 is not the correct answer because it represents a value that is smaller than the result of the subtraction. The operation yields 6/12, which simplifies to 1/2, making 1/4 an incorrect option.

D) 1/6

Option 1/6 is incorrect as it is less than the actual result of the subtraction. After performing the calculation, the result is 6/12, simplifying to 1/2, which is significantly larger than 1/6.

Conclusion

The correct answer is 1/2, as it accurately represents the result of subtracting 3/12 from 9/12. All other options fail to reflect the correct simplification of the fraction resulting from the operation. Thus, 1/2 stands out as the only valid solution.
