Here's how you add

Step 1We can't add two fractions with different denominators (the bottom number). So you need to get a common denominator - both bottom numbers need to match. To do this, you'll multiply the denominators times each other... but the numerators have to change, too. They get multiplied by the other term's denominator. So we multiply 9 by 11, and get 99, then we multiply 100 by 11 and get 1100. Do the same for the second term. We multiply 4 by 100, and get 400, then multiply 100 by 11 and get 1100. So now our fractions look like this:

Step 2Since our denominators match, we can add the numerators. 99 + 400 = 499 Now we have an answer.
