What does 10/7 mean in drug prescription?

Excuse me, could you clarify what the notation "10/7" represents in the context of a drug prescription? Is it a dosage instruction, perhaps indicating the number of pills to be taken in a specific timeframe? Or does it have some other meaning related to the frequency or method of administration? I'm seeking to understand the precise interpretation of this notation in order to ensure accurate medication adherence. Thank you for your assistance.
