Answer

$= \frac{6y^{2}+5x}{xy^{2}}$

Work Step by Step

1) Multiply a fraction with the other denominator to obtain a common denominator between the two fractions. In this case, we multiply the first fraction by $y^{2}/y^{2}$ and the second fraction by $x/x$. $= \frac{6}{x} + \frac{5}{y^{2}}$ $= \frac{6y^{2}}{xy^{2}} + \frac{5x}{xy^{2}}$ $= \frac{6y^{2}+5x}{xy^{2}}$
