Question

How do I simplify (3a^2b / -4xy) x (-5x^2y / 6ab^2)? Please help D; I am so confused with my steps..

Answer 1

3a^2 -5x^2y
---- x -------
-4xy 6ab^2

= a(3ab) -x(5xy)
------- x ---------
2(-2xy) 2b(3ab)

Answer 2

I thought I answered it. :-)

What part is confusing?

Answer 3

Is it that step? I'm so confused..

Answer 4

*3a^2b

Answer 5

is it a^2 b or a^(2b)

Answer 6

Basic concept here is that if there is a variable in the numerator and denominator, you can get rid of that variable. For example, in your equation, you have y in the numerator and y in the denominator. Get rid of it. Then, you have a^2 in the numerator and a in the denominator. So, there will be a left in the numerator. Keep going on, including for constants until nothing else can be cancelled out.

Answer 7

ohh.. i see. ohhh!!

Answer 8

I think I know what you mean! Thank you!

Answer 9

If you want me to confirm your answer, write it out.

Answer 10

Is it like

3a - 5x
------
-24b

Answer 11

You mean (3a) (-5x)/(-24b). You can further simplify by canceling 3 in numerator against 24 in the denominator. Same with the (-1) in the numerator with (-1) in the denominator.

So, you end up with ....?

Answer 12

Is it going to be:
(a-5x)/-8b?

What do you mean by the (-1)?
