help with elastic

A spring A and B are compressed so that they hold equal amounts of elastical potential energy. Calculate the value of the ratio of the compression A to that of B?
Information-The force constants of A are 2times10^4 and B are 1times10^4, the energy stored at 1cm for A is 1J and B is 0.5J, the answer is 0.71 and i have no clue where to start from.

Basically what you want to find is:


Just choose any value as the one where the two elastic potential energies are equal, and then manipulate the equation for elastic potential energy () so that you can get the compression values of each spring.
