please help Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! (3x-6)/(5x-20)*(10x-40)/(27x-54)
I'm going to assume you meant the product of two rational fractions.
---------------------------------------
Factor where you can:
(3(x-2))/(5(x-4))*(10(x-4))/(27(x-2))
------
Cancel factors common to a numerator and a denominator
such as 3,5,(x-4)(x-2) to get:
= (1)/(1(1))*(2(1))/(9(1))
----
= 2/9
