if a > 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 - a ) =
divide(const_1, subtract(add(const_2, const_2), const_1))
let y - z = t - - - > since y is halfway between x and z and x > y we have x - y = t . moreover x - z = ( x - y ) + ( y - z ) = 2 t . similarly since x is halfway between w and z , we have a - x = 2 t . so y - x = - t , y - a = - 3 t . - - - > ( y - x ) / ( y - a ) = 1 / 3 . the answer is ( b ) .
