The more concentrate in the mix is what makes the apple juice "appley". That isn't a word btw. It is a fraction problem, and the highest number would be the correct answer, assuming the fractions would be set up as (concentrate)/(water). Mix W is 5/8 (0.625), X 3/6 (0.5), Y 6/9 (0.66Repeating), and Z 3/5 (0.6). Which number is the largest? (Hint, it's Mix Y) Hope this helps! :)
