If Dale works at full efficiency he needs a break of 1 day after every 2 days of work and he completes a job in a total of 8 days. If he works at reduced efficiency, he can work without break and finish that same job in 8 days. Dale's output at reduced efficiency is what fraction of his output at full efficiency?

This problem repeats another one in the library (at most with different numbers), so it's left out of browsing.
