Answer:

#8,100#

Explanation:

The division by the decimal is the biggest problem here.

Luckily we can get rid of the decimal by multiplying by a power of #10#. We need to multiply it by #1000#

However, we need to multiply the top and bottom by the same number, which is the same as multiplication by #color(blue)(1)#

#16.2/0.002 color(blue)(xx 1000/1000) = 16200/2" "larr# dividing by a whole number

#16200/2 =8,100#
