Answer 1

\[\frac{328\times.045}{(54.2)^2}\]

Answer 2

\[\frac{328\times.045}{(54.2)^2}\approx\frac{300\times.05}{50^2}=\frac{300\times1/20}{50^2}=\]

Answer 3

\[\frac{3\times100}{5^2\times2\times1000}=\]

Answer 4

\[=\frac{3}{5^2\times2}\times\frac1{10}\]

Answer 5

...

Answer 6

@UnkleRhaukus would A be correct?

Answer 7

\[...=\frac3{25\times2}\times\frac1{10}=\frac{3}{50}\times\frac1{10}=\frac35\times\frac1{100}=0.6\times10^{-2}=6\times10^{-3}=A\checkmark\]
