Step 1We still have different denominators (bottom numbers), though, so we need to get a common denominator. This will make the bottom numbers match. Multiply the denominators together first. Now, multiply each numerator by the other term's denominator. Now we multiply 3 by 7, and get 21, then we multiply 64 by 7 and get 448. Now for the second term. You multiply 3 by 64, and get 192, then multiply 64 by 7 and get 448. This gives us a new problem that looks like so:

Step 2Since our denominators match, we can add the numerators. 21 + 192 = 213 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. So next you try the next prime number, which is 13... No good.

So next you try the next prime number, which is 139... No good. So next you try the next prime number, which is 149... No good. So next you try the next prime number, which is 151... No good. So next you try the next prime number, which is 157... No good. So next you try the next prime number, which is 163... No good. So next you try the next prime number, which is 167... No good. So next you try the next prime number, which is 173... No good. So next you try the next prime number, which is 179... No good. So next you try the next prime number, which is 181... No good. So next you try the next prime number, which is 191... No good. So next you try the next prime number, which is 193... No good. So next you try the next prime number, which is 197... No good. So next you try the next prime number, which is 199... No good. So next you try the next prime number, which is 211... No good. So next you try the next prime number, which is 223... No good. 223 is larger than 213. So we're done reducing. And we're done! Here's the final answer to 3/64 + 3/7
