Question 28

The result of subtracting 10.012 by 0.120 is 9.892.

When you subtract 0.120 from 10.012, the calculation yields 9.892, which is the correct answer.

A) 10

This option is incorrect because subtracting 0.120 from 10.012 results in a value less than 10. The correct arithmetic shows that the result is significantly lower than 10.

B) 9.012

This option is also incorrect. When performing the subtraction, 0.120 should be taken away from 10.012, leading to a result that is greater than 9. The correct calculation confirms that this option does not match the expected outcome.

C) 10.122

Option C is incorrect as it suggests an addition rather than a subtraction. The operation of subtracting 0.120 from 10.012 cannot yield a value greater than 10.012, making this answer invalid.

D) 9.892

This is the correct option. The operation 10.012 - 0.120 precisely equals 9.892, confirming that this choice accurately represents the result of the subtraction.

Conclusion

The correct answer, 9.892, is definitively supported by the arithmetic process of subtraction, as it accurately reflects the difference between the two numbers. All other options fail to represent the correct result, either overshooting or undershooting the actual value derived from the calculation.
