Answer: Choice B) 5/8
================================================
Explanation:
There are 10 dots that represent a measurement larger than 1/2 a foot (either the dot is over 5/8 or 3/4 or 7/8). Call this value A, so A = 10.
There are 16 dots total. Call this B, so B = 16.
Divide A over B and then reduce: A/B = 10/16 = 5/8 so that is why the answer is choice B
Coincidentally, we end up with 5/8 but that is not the same as the "5/8" as shown on the chart. It just means that if we had 8 people, the 5 of them would have a foot size larger than half a foot.
