This is how to add


Step 1Since our denominators match, we can add the numerators. 4 + 2 = 6 Now we have an answer.


Step 2Last 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... 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 4/7 + 2/7
