What is 91/1 + 2/12?

Let's add

Step 1Our denominators (bottom numbers) don't match, so we can't add yet. Since 1 is evenly divided by 12, we can multiply just one term to get a common denominator. Multiply 91 by 12, and get 1092, then we multiply 1 by 12 and get 12. The problem now has new fractions to add:

Step 2Since our denominators match, we can add the numerators. 1092 + 2 = 1094 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... Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:
Now, try the same number again. Nope. Try the next prime number, 3... Nope. Try the next prime number, 5... Nope. Try the next prime number, 7... No good. 7 is larger than 6. So we're done reducing. Congratulations! Here's your final answer to 91/1 + 2/12
