I'm having trouble understanding the last sentence.

I set up the equations in the following way:

(1) W=C/3 so W/C = 1/3

(2) C= 5T/4 so C/T = 5/4

to see the relationship between W and T, I multiply equation (1) by 5 and equation (2) by 3 to make C equal

You get W/C = 5/15 and C/T = 15/12 ...therefore W/T = 5/12

Now the last sentence says

**Quote:**

what fraction of the profit from a bushel of wheat is the profit from a bushel of truffles?

. Does this sentence mean what's W/T or T/W? I'm not sure if I'm interpreting the last sentence correctly.
