Let d > c > r > a. If c is twice as far from a as it is from d, and r is twice as far from c as it is from a, then (d - r)/(d - a) = ? Choose one:
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 -r and d -a   d - r= x +2y = 7/2 y   d - a = x + 2x = 3x = 9/2y   7/9ividing both you get: 7/9   Answer 7/9
