Can you cut a cake fairly to solve this middle school math problem?

[Whateverist]

Yeah, this one is harder than the other one, for sure. Don't have the time right now to think about it, but if nobody else solves it within the next few hours, I'll give this a go later.

Maybe we should give our solutions under hide tags so that anyone can still do the problem themselves first if they want?

I'll give my stepson's solution under hide tags after someone else gives the solution, though I expect they'll be the same.  But we're driving to L.A. early tomorrow so I'll give it tonight if it doesn't fall sooner.
