Step 1We have to make sure the denominators are equal. 60 goes into 6 evenly, so we only need to multiply one term to get a common denominator. Multiply 2 by 10, and get 20, then we multiply 6 by 10 and get 60. We now have a new problem, that looks like this:

Step 2Since our denominators match, we can add the numerators. 15 + 20 = 35 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... Are both the numerator and the denominator evenly divisible by 5? Yes! So we reduce it:
So far so good... let's try to divide by that number again. 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. 11 is larger than 7. So we're done reducing. And we're done! Here's the final answer to 15/60 + 2/6
