Step 1Now we need to make our denominators match. 100 goes into 10 evenly, so we only need to multiply one term to get a common denominator. Multiply 9 by 10, and get 90, 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. 100 + 90 = 190 Answer:

Step 3Now, do we need to simplify this fraction? First, we attempt to divide it by 2... Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:
Let's try dividing by that again... Nope! So now we try the next greatest prime number, 3... Nope! So now we try the next greatest prime number, 5... Are both the numerator and the denominator evenly divisible by 5? Yes! So we reduce it:
Let's try dividing by that again... Nope! So now we try the next greatest prime number, 7... Nope! So now we try the next greatest prime number, 11... No good. 11 is larger than 10. So we're done reducing. There you have it! Here's the final answer to 100/100 + 9/10
