+
6
7

Step 1

Since our denominators match, we can add the numerators.

99 + 6 = 105

That gives us the sum, which is

105
7

Step 2

Now, 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...

No good. So next you try the next prime number, which is 7...

Are both the numerator and the denominator evenly divisible by 7? Yes! So we reduce it:

105
7
÷ 7 =
15
1

So far so good... let's try to divide by that number again.

No good. 7 is larger than 1. So we're done reducing.

And we're done! Here's the final answer to 99/7 + 6/7

99
