you asked me about how did i came up with my answer this is what i did:
Write each fraction in simplest form.
#18
(-5x^3y^3)/(-20xy^4)
= (3X(-5)X(x)X(x)X(x)X(y)X(y)X(y))/(2X2X(-5)X(x)X(y)X(y)X(y)X(y))
= after canceling the common terms top and bottom i am left with
= 3 and 2 OF x on top
and 4 and one y on the bottom
thats how i came about my answer.
my answer is: (3x^2)/(4y)
um...can you help me with my math please...?
Here's how I would simplify this one:
-5x^3y^3
--------
-20xy^4
-5/-20 reduces to 1/4; the rest looks OK from what you have done.
Therefore, you end up with this:
x^2
---
4y
I hope this is clear and will help.
