When dissolved in water, glucose (corn sugar) and fructose (fruit sugar) exist in equilibrium as follows:

A chemist prepared a 0.244 M fructose solution at 25°C. At equilibrium, it was found that its concentration had decreased to 0.113 M. (a) Calculate the equilibrium constant for the reaction, (b) At equilibrium, what percentage of fructose was converted to glucose?
