Here's how to add

Step 1Our denominators (bottom numbers) don't match, so we can't add yet. 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. 10 + 6 = 16 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:
Now, try the same number again. Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:
Now, try the same number again. 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 10/12 + 2/4
