Well I thing is -99%. Might not be right. Hope it helps
Take 5/6 x 4/1 and multiply 5x4 and 6x1 to get 20/6. 6 goes into 20 3 times, with 2/6 leftover. Reduce 2/6 to 1/3 and your final answer is 3 1/3.
Answer: Choice D
Explanation:
The range is the set of all possible y outputs of a function. The highest y can go is y = 1, which occurs at the vertex. We can have y = 1 or y be smaller than this. Therefore, the range is 
You would put x over a hundred because you don't know what percent it is then you would put 180 over 240 because the other part of the prapotion is is over of. then you would cross multiply and get 7.5
