What is 28/100 + 1/4?

Here's how to 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 1 by 25, and get 25, then we multiply 4 by 25 and get 100. This gives us a new problem that looks like so:

|||||||||||
Step 2Since our denominators match, we can add the numerators. 28 + 25 = 53 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... No good. 59 is larger than 53. So we're done reducing. Congratulations! Here's your final answer to 28/100 + 1/4
