Here's how you add


Step 1We have to make sure the denominators are equal. Since 6 is evenly divided by 12, we can multiply just one term to get a common denominator. Multiply 3 by 2, and get 6, then we multiply 6 by 2 and get 12. The problem now has new fractions to add:


Step 2Since our denominators match, we can add the numerators. 6 + 5 = 11 This yields the answer


Step 3The last step is to reduce the fraction if we can. To find out, we try dividing 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 11. So we're done reducing. And we're done! Here's the final answer to 3/6 + 5/12
