1. We are given the equation $$\frac{0.25 + 0.125}{0.05} = A.5$$ where $A$ is a digit. 2. First, simplify the numerator: $$0.25 + 0.125 = 0.375$$. 3. Now divide by 0.05: $$\frac{0.375}{0.05} = 7.5$$. 4. We see that $$A.5$$ represents a decimal number with digit $A$ followed by .5, and this equals $$7.5$$. 5. Thus, $A=7$. 6. The additive inverse of $A=7$ is $-7$. 7. So, the answer is option (2) -7.
