Step 1We have to make sure the denominators are equal. Since 2 is evenly divided by 12, we can multiply just one term to get a common denominator. Multiply 80 by 6, and get 480, then we multiply 2 by 6 and get 12. So now our fractions look like this:

||||||||||||||||||
Step 2Since our denominators match, we can add the numerators. 480 + 10 = 490 So the answer is:

||||||||||||||||||
Step 3Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction? 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:
So far so good... let's try to divide by that number again. No good. So next you try the next prime number, which is 3... No good. So next you try the next prime number, which is 5... No good. So next you try the next prime number, which is 7... No good. 7 is larger than 6. So we're done reducing. And we're done! Here's the final answer to 80/2 + 10/12
