What is 9/100 + 2/4?

This is how we add

|||||||||||
Step 1Our denominators (bottom numbers) don't match, so we can't add yet. 100 goes into 4 evenly, so we only need to multiply one term to get a common denominator. Multiply 2 by 25, and get 50, then we multiply 4 by 25 and get 100. We now have a new problem, that looks like this:

Step 2Since our denominators match, we can add the numerators. 9 + 50 = 59 Answer:

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 59. So we're done reducing. Congratulations! Here's your final answer to 9/100 + 2/4
