This is how you add

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 78 by 11, and get 858, then we multiply 92 by 11 and get 1012. Now for the second term. You multiply 10 by 92, and get 920, then multiply 92 by 11 and get 1012. We now have a new problem, that looks like this:

Step 2Since our denominators match, we can add the numerators. 858 + 920 = 1778 That gives us the sum, which is

Step 3Now, do we need to simplify this fraction? First, we attempt to divide it by 2... Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:
