This is how to add


Step 1Can you add yet? Nope! The denominators don't match. We need a common denominator. So next we take both denominators and multiply them. Next, take each numerator and multiply it by the denominator of the other term. So, we multiply 3 by 11, and get 33, then we multiply 6 by 11 and get 66. Now for the second term. You multiply 7 by 6, and get 42, then multiply 6 by 11 and get 66. We now have a new problem, that looks like this:


Step 2Since our denominators match, we can add the numerators. 33 + 42 = 75 Answer:


Step 3Now, do we need to simplify this fraction? First, we attempt to divide it by 2... Nope! So now we try the next greatest prime number, 3... Are both the numerator and the denominator evenly divisible by 3? Yes! So we reduce it:
Let's try dividing by that again... Nope! So now we try the next greatest prime number, 5... Nope! So now we try the next greatest prime number, 7... Nope! So now we try the next greatest prime number, 11... Nope! So now we try the next greatest prime number, 13... Nope! So now we try the next greatest prime number, 17... Nope! So now we try the next greatest prime number, 19... Nope! So now we try the next greatest prime number, 23... No good. 23 is larger than 22. So we're done reducing. There you have it! Here's the final answer to 3/6 + 7/11
