Here's 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 12, and get 936, then we multiply 92 by 12 and get 1104. Now for the second term. You multiply 5 by 92, and get 460, then multiply 92 by 12 and get 1104. We now have a new problem, that looks like this:

Step 2Since our denominators match, we can add the numerators. 936 + 460 = 1396 Answer:

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:
Now, try the same number again. Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:

So we're done reducing. Congratulations! Here's your final answer to 78/92 + 5/12
