#3abc#

Explanation:

There are several ways to multiply and simplify this expression... Hopefully you'll understand how I do it...

Step 1) Simplify each fraction as a whole fraction

#(4a^2b)/(b^2c)*(6b^4c^2)/(8ab^2)#

#=(4a^2)/(bc)*(3b^2c^2)/(4a)#

Step 2) Cross multiply

#=a/(bc)*3b^2c^2#

#=a*3bc#

Step 3) Multiply

#=3abc#
