Start out with the fraction as written. The wherever there is a negative exponent, swap between numerator and denominator:
(2x^{5}y^{4}z^{3}/x^{1}y^{5}z^{5})^{1}
Invert the fraction:
= x^{1}y^{5}z^{5}/2x^{5}y^{4}z^{3}
= y^{5}z^{}/2x^{}x^{}y^{}z^{}
= y^{}z^{}/2x^{}y^{}z^{}
Now subtract exponents, leaving the larger portion where it is:
yz^{}/2x^{}

Oops. Lost track of the exponents:
...
y^5 z^5 / 2x^5 x^1 y^4 z^3
y^5 z^5 / 2x^6 y^4 z^3
yz^2/2x^6
