Question 75942
simplifying complex fractions:

           x-xy -¹ / 1 + x/y   
      {{{(x-xy^(-1))/(1+x/y)}}}
{{{(x-x/y)/(1+x/y)}}}  Multiply the top and bottom by the LCD y
{{{y(x-x/y)/(y(1+x/y))}}}
{{{(xy-xy/y)/(y+xy/y)}}}
{{{highlight((xy-x)/(y+x))}}}  or {{{highlight(x(y-1)/(x+y))}}}
Happy Calculating!!!!
