The answer choices suggest that we don't need to be very precise. A very rough approximation should be good enough.

So, let's do some rounding:

\(\frac{(0.4903)*(5.548)}{(0.301)}\)

\(\frac{(0.5)*(6)}{(0.3)}\)

\(\frac{3}{0.3}\)

\(\frac{30}{3}\) = 10

The only answer anywhere close to this is (C), 9.

Estimating we have:

(0.5 x 5.4)/0.3 = 2.7/0.3 = 9

Answer: C
