This is how to add


Step 1We have to make sure the denominators are equal. Since 4 is evenly divided by 12, we can multiply just one term to get a common denominator. Multiply 2 by 3, and get 6, then we multiply 4 by 3 and get 12. So now our fractions look like this:


Step 2Since our denominators match, we can add the numerators. 6 + 2 = 8 Now we have an answer.


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... Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:
So far so good... let's try to divide by that number again. Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:
So far so good... let's try to divide by that number again. No good. So next you try the next prime number, which is 3... No good. 3 is larger than 2. So we're done reducing. And we're done! Here's the final answer to 2/4 + 2/12
