The expression 0.625 can be rewritten as 5/8 because 6 is in the tenths place and 2 is in the hundredths place. Therefore, the expression becomes:

5/8 + 3/4

To add these fractions, we need to find a common denominator. In this case, the least common denominator (LCD) is 8. So, we need to rewrite 3/4 as an equivalent fraction with a denominator of 8:

3/4 = (3/4) * (2/2) = 6/8

Now, the expression becomes:

5/8 + 6/8

Adding the numerators together gives:

5 + 6 = 11

The denominator remains the same:

8

Therefore, the simplified expression is 11/8.

So, the answer is A) 11/8.
