Answer:
The answer is C, 14 inches(i think, look at another answer to confirm, I'm not always right, I am only human)
Explanation:
What you do is you take each fraction and divide each fraction, like
you take 1 divided by 8 and you get 0.125. If they are smaller than or equal to 0.4444444444, then you round down(keep the integer in the mixed number). If they are greater than 0.4444444, than you add 1 to the integer, the next whole number up. Now you add your rounded numbers up and you should get 14.
