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