This is how we add


Step 1Our denominators (bottom numbers) don't match, so we can't add yet. Since 2 is evenly divided by 4, we can multiply just one term to get a common denominator. Multiply 1 by 2, and get 2, then we multiply 2 by 2 and get 4. The problem now has new fractions to add:


Step 2Since our denominators match, we can add the numerators. 2 + 3 = 5 This yields the answer


Step 3The last step is to reduce the fraction if we can. To find out, we try dividing it by 2... Nope. Try the next prime number, 3... Nope. Try the next prime number, 5... No good. 5 is larger than 4. So we're done reducing. Congratulations! Here's your final answer to 1/2 + 3/4
