Answer: 2/5
Explanation: 10+8+12 = 30 12/30 = .4 .4 = 2/5
given: 
$\therefore Ac=\frac{(2)2}{2}=2$
Well 85% of 25 is 21.25. So the closest ones would be 20 or 22. Well let's check out the difference's. 21.25-20= 1.25.....22-21.25=.75. well clearly .75 is smaller than 1.25 so your answer would be 22. 85% of 25 is closest to 22.
