Math team (please read)!!

<p>for those of you that does the math league problems
I just finished the November 17th, 2009 problems
and I have a question</p>

<p>the last question was about the betting between A1 and B0
and how the sum of their money was 168 dollars
and that each bet the same fraction of his money...
can you please tell me how to solve that question?
I know the answer, but I don't know how to solve them..
my teacher never told me how to solve them
and its been bugging me ever since haha
thanks.</p>
