12 + y

--------
36 + w

To simplify the expression (12 + y) divided by (36 + w), we need to combine the terms and determine if there are any common factors that can be canceled out.

The first step is to combine "12" and "y" as they share no common factors. So we have:

(12 + y) / (36 + w)

Next, we can see that the denominator "36" and "w" also share no common factors. Therefore, we cannot simplify the expression further using common factors.

Hence, the simplification of (12 + y) / (36 + w) is:

(12 + y) / (36 + w)
