Step 1Of course, you can't add two fractions if the denominators (bottom numbers) don't match. To get a common denominator, multiply the denominators together. Then we fix the numerators by multiplying each one by their other term's denominator. Now you multiply 91 by 11, and get 1001, then we multiply 6 by 11 and get 66. Do the same for the second term. We multiply 10 by 6, and get 60, then multiply 6 by 11 and get 66. The problem now has new fractions to add:

Step 2Since our denominators match, we can add the numerators. 1001 + 60 = 1061 The sum we get is

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... Nope. Try the next prime number, 17... Nope. Try the next prime number, 19... Nope. Try the next prime number, 23... Nope. Try the next prime number, 29... Nope. Try the next prime number, 31... Nope. Try the next prime number, 37... Nope. Try the next prime number, 41... Nope. Try the next prime number, 43... Nope. Try the next prime number, 47... Nope. Try the next prime number, 53... Nope. Try the next prime number, 59... Nope. Try the next prime number, 61... Nope. Try the next prime number, 67... No good. 67 is larger than 66. So we're done reducing. Congratulations! Here's your final answer to 91/6 + 10/11
