If g > x > y > z on the number line, y is halfway between x and z, and x is halfway between w and z, then (y - x)/(y - g) = Choose the correct choice from the following.
A) 1/4  B) 1/3  C) 1/2  D) 3/4  E) 1
Let y-z=t ---&gt; since y is halfway between x and z and x&gt;y we have x-y=t. Moreover x-z=(x-y)+(y-z)=2t. Similarly since x is halfway between w and z, we have g-x=2t. So y-x=-t, y-g=-3t. ---&gt; (y - x)/(y - g) = 1/3.   The answer is (1/3).
