## anonymous 4 years ago multiply or divide as indicated and reduce to lowest terms where appropriate: 2x-4/5x X 15x/x-2 multiply or divide as indicated and reduce to lowest terms where appropriate: 2x-4/5x X 15x/x-2 @Mathematics

how the hell?!

2. anonymous

I assume that is $\frac{2x-4}{5x}\frac{15x}{x-2}$ right?

3. anonymous

You can rewrite that like this... $\frac{2(x-2)}{5x}\frac{3(5x)}{x-2}$ which would be six, no?

4. anonymous

correct how did u write it like that? i cant write it like that in the question box

5. anonymous

but i dont know how you are even re writing it

6. anonymous

It's called LaTeX, don't worry about it. And just look at it, I dunno what else to tell you really. 2x-4 = 2(x-2), right?

7. anonymous

yes

8. anonymous

So, the (x-2)'s cancel, and the 5x's cancel, leaving you with 2*3 = 6.

9. anonymous

ohhhhh okay thank you!

10. anonymous

so what about -8 X n/-3msquared

11. anonymous

you can cancel the negative signs.

12. anonymous

this is such hard math

13. anonymous

i dont know how to calculate algebraic functions

14. anonymous

Such as?

15. anonymous

i dont know to write it

16. anonymous

(5/pqSQUARED) ( -3pCUBEDr/10q)

17. anonymous

$\frac{5}{pq^2}\frac{-3p^3r}{10q}$ ?

18. anonymous

how do u do that?

19. anonymous

You'll notice the "Equation" button just below the text box.

20. anonymous

i see it but i havent figured out how to work it

21. anonymous

It's a document typesetting language called LaTeX. If you can't work the buttons don't worry about it because what I just typed looks like this: "\frac{5}{pq^2} \frac{-3p^3r}{10q} "

22. anonymous

I understood what you meant well enough when you just typed it.

23. anonymous

okie doke

24. anonymous

And to answer your question, that would be $\frac{-15p^3r}{10pq^3} = \frac{-3p^2r}{2q^3}$

25. anonymous

can you explain how you got that?

26. anonymous

I can tell you that when you multiply fractions, you multiply the numerators and denominators together, and that 15 and 10 share a common factor of 5 so that reduces to 3/2 when you cancel it, and p^3 / p = p^2, but besides that, I apologize, I do not know how to explain it further.

27. anonymous

thanks i just not that good at math
