Here's how you add
Since our denominators match, we can add the numerators.
1 + 8 = 9
That gives us an answer of
Can this fraction be reduced?
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...
No good. 5 is larger than 3. So we're done reducing.
There you have it! Here's the final answer to 1/12 + 8/12
