Question 1197736
Fred and Tom mowed lawns for a day. Fred earned x/y times as much money as did Tom.  

Determine what fraction of total money earned was Tom's.

Not sure how to solve.
<pre>Let amount Tom earned, be T
Since Fred earned {{{x/y}}} times as much money as did Tom, Fred earned {{{(x/y)T}}}.  
Together, they made: {{{matrix(1,3, T + (x/y)T, or, T(1 + x/y))}}}

Fraction of total money, earned by Tom: {{{highlight_green(matrix(1,7, T/T(1 + x/y), "=", 1cross(T)/1cross(T)(1 + x/y), "=", highlight(1/(1 + x/y)), or, highlight(y/(y + x))))}}}</pre>
