Cancel \({y}^{2}\).
\[\frac{12{x}^{5}}{15{x}^{4}}\]
Take out the constants.
\[\frac{12}{15}\times \frac{{x}^{5}}{{x}^{4}}\]
Simplify \(\frac{12}{15}\) to \(\frac{4}{5}\).
\[\frac{4}{5}\times \frac{{x}^{5}}{{x}^{4}}\]
Use Quotient Rule: \(\frac{{x}^{a}}{{x}^{b}}={x}^{a-b}\).
\[\frac{4{x}^{5-4}}{5}\]
Simplify \(5-4\) to \(1\).
\[\frac{4{x}^{1}}{5}\]
Use Rule of One: \({x}^{1}=x\).
\[\frac{4x}{5}\]
(4*x)/5
