## anonymous 5 years ago How do I reduce this fraction: y/x+x/y / 1/xy

1. anonymous

combine fractions in numerator y/x + x/y = (y^2+x^2)/xy multiply by reciprocal of denominator (y^2+x^2)/xy * xy/1 = y^2 + x^2

2. anonymous

$\frac{\frac{y}{x}+\frac{x}{y}}{\frac{1}{x y}}=\frac{\frac{x^2+y^2}{x y}}{\frac{1}{x y}}=x^2+y^2$

3. anonymous

yeah that looks better

4. anonymous

Hey guys, I'm new here. How did robtobey write that? The Equation editor has no fractions???

5. anonymous

i wish i knew too

This is a test {2}{3}

7. anonymous

This is a test frac{2}{3}

8. anonymous

This is a test \frac{2}{3}

9. anonymous

This is a test [\frac{2}{3}]

Mathematic 8 will copy and paste LaTex. it is done in two steps. First right click on the Mathematica expression. Then holding down the right click button, slide down to the Copy As which puts up a secondary window offering Copy As LaTex or MathML. Considering the technology embedded in this program and the years of development, they essentially give it away to students and teachers.

$\frac{\frac{3}{y}}{\frac{2}{x}+1}$

Thank you robtobey. I will read this and look into it...

I don't have Mathemataica at our college.

I'm clicking on Equation editor and using the LaTeX frac{a}{b} command.

15. anonymous

I can learn the LaTeX commands on an as-needed basis, as I go along.

$\dfrac{x}{y}$
