Step 1We have to make sure the denominators are equal. 100 goes into 10 evenly, so we only need to multiply one term to get a common denominator. Multiply 6 by 10, and get 60, then we multiply 10 by 10 and get 100. We now have a new problem, that looks like this:

Step 2Since our denominators match, we can add the numerators. 15 + 60 = 75 Answer:

Step 3Now, do we need to simplify this fraction? First, we attempt to divide it by 2... No good. So next you try the next prime number, which is 3... No good. So next you try the next prime number, which is 5... Are both the numerator and the denominator evenly divisible by 5? 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 5? Yes! So we reduce it:
So far so good... let's try to divide by that number again. No good. 5 is larger than 3. So we're done reducing. And we're done! Here's the final answer to 15/100 + 6/10
