What is 22/60 + 9/12?

Here's how you add

|||||||||||
Step 1Our denominators (bottom numbers) don't match, so we can't add yet. 60 goes into 12 evenly, so we only need to multiply one term to get a common denominator. Multiply 9 by 5, and get 45, then we multiply 12 by 5 and get 60. We now have a new problem, that looks like this:

|||||||||||
Step 2Since our denominators match, we can add the numerators. 22 + 45 = 67 That gives us the sum, which is

|||||||||||
Step 3Now, do we need to simplify this fraction? 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... Nope. Try the next prime number, 19... Nope. Try the next prime number, 23... Nope. Try the next prime number, 29... Nope. Try the next prime number, 31... Nope. Try the next prime number, 37... Nope. Try the next prime number, 41... Nope. Try the next prime number, 43... Nope. Try the next prime number, 47... Nope. Try the next prime number, 53... Nope. Try the next prime number, 59... Nope. Try the next prime number, 61... No good. 61 is larger than 60. So we're done reducing. Congratulations! Here's your final answer to 22/60 + 9/12
