Let d > c >e > a. If c is twice as far from a as it is from d, and e is twice as far from c as it is from a, then (d - e)/(d - a) = ?
Choose the correct choice from the following answers
A) 2/9  B) 1/3  C) 2/3  D) 7/9  E) 3/2
Draw a number line and label with x and y. You would have:   Before calculating recognize it would be more effcient to express x or y in terms of the other. here 2x = 3y so x =3/2 y.   Now you can calculate d -e and d -a   d - e= x +2y = 7/2 y   d - a = x + 2x = 3x = 9/2y   7/9ividing both you get: 7/9   Answer 7/9
