Step 1Our denominators (bottom numbers) don't match, so we can't add yet. Since 3 is evenly divided by 12, we can multiply just one term to get a common denominator. Multiply 34 by 4, and get 136, then we multiply 3 by 4 and get 12. The problem now has new fractions to add:

Step 2Since our denominators match, we can add the numerators. 136 + 9 = 145 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... Nope. Try the next prime number, 3... Nope. Try the next prime number, 5... Nope. Try the next prime number, 7... Nope. Try the next prime number, 11... Nope. Try the next prime number, 13... No good. 13 is larger than 12. So we're done reducing. Congratulations! Here's your final answer to 34/3 + 9/12
