Let's add

Step 1Our denominators (bottom numbers) don't match, so we can't add yet. Since 4 is evenly divided by 48, we can multiply just one term to get a common denominator. Multiply 3 by 12, and get 36, then we multiply 4 by 12 and get 48. So now our fractions look like this:

||||||||||||||||||
Step 2Since our denominators match, we can add the numerators. 9 + 36 = 45 So the answer is:

||||||||||||||||||
Step 3Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction? To find out, we try dividing it by 2... Nope. Try the next prime number, 3... Are both the numerator and the denominator evenly divisible by 3? Yes! So we reduce it:
Now, try the same number again. 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 9/48 + 3/4
