This is how we add


Step 1We have to make sure the denominators are equal. 9 goes into 3 evenly, so we only need to multiply one term to get a common denominator. Multiply 2 by 3, and get 6, then we multiply 3 by 3 and get 9. This gives us a new problem that looks like so:


Step 2Since our denominators match, we can add the numerators. 6 + 3 = 9 That gives us an answer of


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... Are both the numerator and the denominator evenly divisible by 3? Yes! So we reduce it:
So far so good... let's try to divide by that number again. Are both the numerator and the denominator evenly divisible by 3? Yes! So we reduce it:
So far so good... let's try to divide by that number again. No good. 3 is larger than 1. So we're done reducing. And we're done! Here's the final answer to 2/3 + 3/9
