Answer:

13/8 or 1 1/2

Explanation:

Step 1

Since our denominators match, we can add the numerators.

7 + 6 = 13

So what's the answer so far?

13/8

Step 2

Can this fraction be reduced?

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 8. So we're done reducing.

And we're done! Here's the final answer to 7/8 + 6/8
