Answer:
I believe the answer would be 121.
Explanation:
First off, I don't believe this is French, exactly. It seems more like math. But regardless. What I did to do this: I divided 363 by 3 and got 121. I did use a calculator so I cannot give you a step by step way that I did this. Anyway, 121 is a multiple of 11 so therefore, you have your answer. Have a nice day.
