Fractions do not have questions and therefore do not have answers.
Perhaps you would like it reduced or simplified?
Is this the fraction?

Learn to write in math talk and use plenty of parentheses
Your problem can be interpreted many ways
x^(-2)/(x^(-1)-x^(-2))
The key is that x^(-2)=1/x^2
and x^(-1)=1/x
so we redo the equation

multiply through by x^2/x^2
1/(x-1)
BTW we could have multiplied by x^2/x^2 in the beginning without redoing.
x^(-2)/(x^(-1)-x^(-2))
1/x-1
Remember that x^(-2)*x^(2)=x^0=1
so the final result is 1/(x-1)
