A (5 & 1/5) YOUR ANSWER

This choice is incorrect because it suggests a result that is greater than the actual answer. If we were to calculate 12 - 7 (which is 5) and then incorrectly add the fraction, it would not yield the correct result.

This choice is incorrect because it misrepresents the total after performing the subtraction. The result should be less than 5, as we are subtracting a larger number (7 4/5) from 12, making this option invalid.

D (4 & 1/5) CORRECT

This is the correct answer, as it accurately represents the result of the subtraction. After converting 7 4/5 to an improper fraction and performing the calculation, we find that 12 - 7 4/5 equals 4 & 1/5.
