If E partitions CD by a ratio of 1/8, then which of the following could be the location of E?

You neglected to copy the choices that are given along with the

question, so It's hard for us to steer you toward the correct one.

But take heart ... all is not lost! As hard as you might try to keep

us from discovering the correct answer, the people who answer

questions on this website are so good that we can often determine

the correct answer without even seeing the choices!

If 'E' partitions 'CD' in the ratio of 1/8, then 'E' must be located exactly

one ninth of the distance from 'C' to 'D'. Then the piece on one side

of 'E' is 1/9 of the total distance, and the piece on the other side of it

is the other 8/9 of the total distance. The ratio of the pieces is then

(1/9) / (8/9) = 1/8.
