Step 1Our denominators (bottom numbers) don't match, so we can't add yet. Since 6 is evenly divided by 12, we can multiply just one term to get a common denominator. Multiply 91 by 2, and get 182, then we multiply 6 by 2 and get 12. So now our fractions look like this:

Step 2Since our denominators match, we can add the numerators. 182 + 3 = 185 So the answer is:

|||||||||||
Step 3Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction? 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 91/6 + 3/12
