<u>Answer:</u>

-2\frac{3}{8}

<u>Step-by-step explanation:</u>

We are given the following expression and we are to solve it:

\frac{-\frac{3}{4} -\frac{1}{5} }{\frac{2}{5} }

Firstly, we will take the LCM of the fractions in the denominator to make it a single fraction and then solve further:

\frac{\frac{-3(5)-1(4)}{20} }{\frac{2}{5} }

\frac{\frac{-15-4}{20} }{\frac{2}{5}}

\frac{-\frac{19}{20} }{\frac{2}{5} }

Changing the division into multiplication by taking a reciprocal of the denominator:

-\frac{19}{20} *\frac{5}{2}

-\frac{19}{8}

-2\frac{3}{8}

2x^2 / x^2 - y^2 - x^2 / xy - y ^ 2​
Juliette [100K]

Answer:

2 - 2y^2 - x/y

Step-by-step explanation:

2x^2/x^2 = 2

and

x^2/xy = x/y

therefore

2x^2/x^2 - y^2 - x^2/xy - y^2

= 2 - y^2 - x/y - y^2

= 2 - y^2 - y^2 - x/y

= 2 - 2y^2 - x/y
