C.
If each 1/2 is cut in 4 than you would have to multiply that by 2 because it's only half. Then since you're finding what fraction is it you would put a 1 on top and say 1/8.
The vertex would be at (3, 6).
66.6667%
Now we can see that our fraction is 66.666666666667/100, which means that 4:6 as a percentage is 66.6667%.
Take a picture of the graph then re- upload the question with the same words from this one. without it i cannot solve the problem and the whole math equation relies on that graph which isn't here
