Hi;
I am going to be the first to conjecture an infinite amount. Here are 30

Re: Crazy Fractions!!!
Can you prove your conjecture?

That might be very difficult or impossible to do. I do not know yet.

Re: Crazy Fractions!!!
I found that the equation above is equivalent to:
There seem to be no solutions with the given restrictions .

I posted 30 solutions and there are more.

Re: Crazy Fractions!!!
I checked the first of them and it's not correct.The same probably goes for the other ones as well.

Re: Crazy Fractions!!!
You changed the problem! It is different in the other thread!
This one is trivial. Of course there is no solutions.

They solve probability problems mostly. I show by example and leave the theorems to guys who hate numbers.

Nope, they are solved by computation. Do you have access to some computational engine?
