The first part of the question gives you the proportion of flour to milk to use.

It 6 to 1 1/6 of flour to milk.

Let's start by rewriting the mixed fraction into a fraction.

1 and 1/6 means:


1+(1)/(6)=(6)/(6)+(1)/(6)=(7)/(6)

Now, we know the proportion is 6 to 7/6.

To get the amount of milk for 2 cups of flour, notice that we divided the original amount of flour by 3, because 6/3 = 2.

To maintain the proportion of flour to milk, we need to divide the amount of milk by 3 too:


((7)/(6))/(3)=((7)/(6))/((3)/(1))=(7)/(6)\cdot(1)/(3)=(7)/(18)

So, the amount of milk for 2 cups of flour is 7/18 cups.
