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.
