Only read the first 4 problems.
1 and 4 have no answer and I doubt teaching math by utilizing
logic fallacies does any good.
First depends on potential subdivision.
Fourth depends on the fill level of the vessels.
Don't think that is the right way to teach anything.
I don't think the answer to 4 depends on the fill level of the vessels. All that matters is that the volumes of the liquids in the barrel and the glass are unchanged, so that volumes of the foreign liquids will be equal.
> Fourth depends on the fill level of the vessels.
I don't think it does. I would suggest trying different ratios of liquids on the second spoon to get an understanding of why the solution turns out to be what it is.
