Try 4.5 inches. You take 18, divide it by four you get 4.5. I divided by 4 because of the 1/4 inch by 1 foot. Minus 2 from 18, you get the next closest dividend of 4 and that's 16. 16 divided by 4 is 4. 2 are left over to make .5. you get 4.5
Well I tried sloving it and I got 1.5
2.32 is 2.9% of 80, so 2.9% is your answer. Hope this helped!
