### Goo Be Gone Table 2

We do not understand the final Table 2 "Average Ratio of Water to Oil question." For example, if we do 3 trials of a sorbant such as fur and our starting total water to oil level is 4 cups (3 c water, 1 c oil) and we get the following results:
Trial 1: Total water and Oil Level (A) 3.5 cups, Remaining Water Level After Removing Sorbant (B) 3 cups, Remaining Oil Level after removing sorbant (A-B) 1/2 cups, what is the ratio of remaining water divided by remaining oil (B/(A-B)) and what does that tell us? And finally if in the 3rd trail: Total water and Oil Level (A) 2.5 cups, Remaining Water Level After Removing Sorbant (B) 2 cups 3.5oz, Remaining Oil Level after removing sorbant (A-B) 1/2oz, what is the final ratio of remaining water divided by remaining oil (B/(A-B))?

The ratio is B / (A-B) = 3 / (0.5) = 6.
Because your ideal sorbant will remove oil without removing water, it's nice to have a single number that reflects both of these results. A high ratio of remaining water to oil means that there is plenty of water left and little oil, while a low ratio means not much water but lots of oil remains. Your starting ratio (no sorbant) is 3 / 1 = 3. Thus, a ratio higher than 3 means a sorbant did what you hoped and removed oil, while a ratio lower than 3 means it removed more water than oil.
