Step 1Our denominators (bottom numbers) don't match, so we can't add yet. 15 goes into 5 evenly, so we only need to multiply one term to get a common denominator. Multiply 4 by 3, and get 12, then we multiply 5 by 3 and get 15. This gives us a new problem that looks like so:

Step 2Since our denominators match, we can add the numerators. 25 + 12 = 37 That gives us an answer of
|
|||||||||||
Step 3Can this fraction be reduced? First, we attempt to divide it by 2... Nope. Try the next prime number, 3... Nope. Try the next prime number, 5... Nope. Try the next prime number, 7... Nope. Try the next prime number, 11... Nope. Try the next prime number, 13... Nope. Try the next prime number, 17... No good. 17 is larger than 15. So we're done reducing. Congratulations! Here's your final answer to 25/15 + 4/5
