Best ResponseYou've already chosen the best response.1are you sure that 1/8 is the ratio?

Best ResponseYou've already chosen the best response.1because if it is, we won't land exactly on any of those numbers in the answer choices

Best ResponseYou've already chosen the best response.1we have 16 units to divide into 1+8=9 parts, and then we'll take 1/9 of those parts from an endpoint to find our partition.

Best ResponseYou've already chosen the best response.0ok so how do i do that?

Best ResponseYou've already chosen the best response.1possibly the problem expects you to choose 7 as your answer, but that isn't strictly speaking correct. partition CD by 1/8 means that CE and ED have the ratio 1:8, which means we must chop CD into 9 equal parts, and place E 1 part toward D from C. CD goes from 9 to +7 in your diagram, which is a total of 16 units. 16/(8+1) = 16/9 and neither 1*16/9 nor 8*16/9 is a round number, yet all the answer choices are round numbers.

Best ResponseYou've already chosen the best response.116/9 = 1.77777777... so if we add 9 + 1.777777... we get 7.22222... which is close to 7, but not the same. But all the other answers are even further removed from the 1/8 point, so that's the best of the bunch, I suppose.

Best ResponseYou've already chosen the best response.1If the ratio was 1/7, then we could do the problem correctly. CD is 16 units long, divided into 1+7=8 parts gives us 2 units per part. Our ratio calls for us to go 1 part = 2 units toward D from C, so 9 + 2 = 7 and that is exactly what one of the answer is. That's what made me ask if you had copied the problem correctly (you had, but I think the problem is incorrect. It happens much more often than it should, given what textbook publishers charge!)

Best ResponseYou've already chosen the best response.1Yes, that would be good. If they insist that the problem is correct as written, let me know and I will supply you with some problems for them that demonstrate the flaw in their understanding :)
