Step 1Our denominators (bottom numbers) don't match, so we can't add yet. Since 2 is evenly divided by 36, we can multiply just one term to get a common denominator. Multiply 1 by 18, and get 18, then we multiply 2 by 18 and get 36. So now our fractions look like this:

|||||||||||
Step 2Since our denominators match, we can add the numerators. 25 + 18 = 43 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... 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... No good. 37 is larger than 36. So we're done reducing. Congratulations! Here's your final answer to 25/36 + 1/2
