A batch of cookies was divided amomg 2 tins: 2/3 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	Answers.
A) 15/2
B) 9/4
C) 5/11
D) 7/5
E) 9/7
This will help reduce the number of variables you have to deal with:   G + B = 2/3   R = 1/2   B = 1/4   We can solve for G which is 5/12   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*(5/12 + 1/2) = 5/12   X = 5/11   ANSWER: C. 5/11
