What was the ratio of the two isotopes

Two billion years ago a uranium deposit in Oklo (Africa) spontaneously underwent nuclear fission. This was determined by depletion of Uranium-235 in uranium ore from the region. The atomic ratio of Uranium-235 to Uranium-238 in current uranium is 1:139. What was the ratio of these two isotopes when the natural reactor went critical. Show your work.
