Billy saw 6 tigers and 9 lions at the zoo. What is the ratio of tigers to lions that Billy saw, and what is the
significance of this ratio?
A. 1:3, because the cats Billy saw were in groups of threes
B. 2:3, because Billy saw two-thirds as many tigers as lions
C. 2:3, because two-thirds of the cats Billy saw were tigers
D. 1:3, because Billy saw 3 fewer tigers than lions at the zoo
The correct ratio is 1;3 so that eliminates B and C. The problem doesn't state anything about Billy seeing groups of tigers so D is the only logical answer.
