A batch of cookies was divided amomg 3 tins: 3/4 of all the cookies were placed in either the blue or the green tin, and the rest were placed in the red tin. If 1/4 of all the cookies were placed in the blue tin, what fraction of the cookies that were placed in the other tins were placed in the green tin Pick.
A) 15/2	B) 9/4	C) 5/9	D) 3/5	E) 9/7
This will help reduce the number of variables you have to deal with:   G + B = 3/4   R = 1/3   B = 1/4   We can solve for G which is 1/2   What fraction (let it equal X) of the cookies that were placed in the other tins were placed in the green tin?   So..   X*(G+R)=G   X*(1/2 + 1/3) = 1/2   X = 3/5   ANSWER: 3/5
