Step 1Our denominators (bottom numbers) don't match, so we can't add yet. Since 1 is evenly divided by 11, we can multiply just one term to get a common denominator. Multiply 12 by 11, and get 132, then we multiply 1 by 11 and get 11. The problem now has new fractions to add:

Step 2Since our denominators match, we can add the numerators. 132 + 10 = 142 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 11. So we're done reducing. Congratulations! Here's your final answer to 12/1 + 10/11
