Step 1Can you add yet? Nope! The denominators don't match. We need a common denominator. So next we take both denominators and multiply them. Next, take each numerator and multiply it by the denominator of the other term. So, we multiply 91 by 11, and get 1001, then we multiply 6 by 11 and get 66. Now for the second term. You multiply 7 by 6, and get 42, then multiply 6 by 11 and get 66. We now have a new problem, that looks like this:

Step 2Since our denominators match, we can add the numerators. 1001 + 42 = 1043 Answer:

Step 3Now, do we need to simplify this fraction? First, we attempt to divide 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 + 7/11
