What is 80/2 + 9/10?

This is how we add

Step 1We have to make sure the denominators are equal. 10 goes into 2 evenly, so we only need to multiply one term to get a common denominator. Multiply 80 by 5, and get 400, then we multiply 2 by 5 and get 10. This gives us a new problem that looks like so:

Step 2Since our denominators match, we can add the numerators. 400 + 9 = 409 So what's the answer so far?

Step 3Can this fraction be reduced? First, we attempt to divide it by 2... 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. So next you try the next prime number, which is 11... No good. 11 is larger than 10. So we're done reducing. And we're done! Here's the final answer to 80/2 + 9/10
