Answer:

\dfrac{-y(2x^2 + y)}{x(6x - 5y^2)}

Step-by-step explanation:

\dfrac{\frac{1}{x^2}+\frac{2}{y}}{\frac{5}{x}-\frac{6}{y^2}} =

To eliminate the denominators of the main numerator and denominator, we multiply the numerator and denominator of the main fraction by the LCD of all small denominators.

The LCD of x^2, y, x, and y^2 is x^2y^2.

= \dfrac{x^2y^2 \times (\frac{1}{x^2}+\frac{2}{y})}{x^2y^2 \times (\frac{5}{x}-\frac{6}{y^2})}

= \dfrac{y^2 + 2x^2y}{5xy^2 - 6x^2}

= \dfrac{y(y + 2x^2)}{x(5y^2 - 6x)}

= \dfrac{-y(2x^2 + y)}{x(6x - 5y^2)}

One way to find a common denominator is by
Lena [83]

Answer:

Step-by-step explanation:

a). 1\frac{3}{5}=1+\frac{3}{5}

         =1+\frac{3}{5}\times \frac{4}{4}

         =1+\frac{12}{20}

         =1\frac{12}{20}

   1\frac{3}{4}=1+\frac{3}{4}

        =1+\frac{3}{4}\times \frac{5}{5}

        =1+\frac{15}{20}

        =1\frac{15}{20}

Therefore, common denominator of 20.

b). 2\frac{1}{2}=2+\frac{1}{2}

         =2+\frac{1}{2}\times \frac{5}{5}

         =2+\frac{5}{10}

         =2\frac{5}{10}

     \frac{4}{5}=\frac{4}{5}\times \frac{2}{2}

        =\frac{8}{10}

Common denominator of 10.

c). \frac{3}{8}=\frac{3}{8}\times \frac{6}{6}

       = \frac{18}{48}

   \frac{1}{6}=\frac{1}{6}\times \frac{8}{8}

      = \frac{8}{48}

Common denominator of 48.
