Step 1Our denominators (bottom numbers) don't match, so we can't add yet. 72 goes into 8 evenly, so we only need to multiply one term to get a common denominator. Multiply 1 by 9, and get 9, then we multiply 8 by 9 and get 72. This gives us a new problem that looks like so:

|||||||||||
Step 2Since our denominators match, we can add the numerators. 100 + 9 = 109 So what's the answer so far?

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... 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... Nope. Try the next prime number, 67... Nope. Try the next prime number, 71... Nope. Try the next prime number, 73... No good. 73 is larger than 72. So we're done reducing. Congratulations! Here's your final answer to 100/72 + 1/8
