This is how we add


Step 1Since our denominators match, we can add the numerators. 1 + 2 = 3 That gives us an answer of


Step 2Can 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. 5 is larger than 3. So we're done reducing. And we're done! Here's the final answer to 1/7 + 2/7
