\(\frac{39,897*0.0096}{198.76}\)

If moving decimal points isn't your first choice, round the numbers and use powers of 10:

40,000 = 4 * 10\(^4\)

.01 = 1 * 10\(^{-2}\)

200 = 2 * 10\(^2\)

\(\frac{(4*10^4)*(1*10^{-2})}{(2*10^2)}\)

\(\frac{(4*10^4)}{(2*10^2)*(1*10^2)}\)

\(\frac{4*10^4}{2*10^{(2+2)}}\)

\(\frac{4*10^4}{2*10^4} = 2\)

Answer C
