Step 2Since our denominators match, we can add the numerators. 108 + 7 = 115 Answer:

Step 3Now, do we need to simplify this fraction? First, we attempt to divide it by 2... No good. So next you try the next prime number, which is 3... No good. So next you try the next prime number, which is 5... No good. So next you try the next prime number, which is 7... No good. So next you try the next prime number, which is 11... No good. So next you try the next prime number, which is 13... No good. 13 is larger than 12. So we're done reducing. And we're done! Here's the final answer to 36/4 + 7/12
