First scan the answer choices.
Since they're spread apart, we can estimate AGGRESSIVELY (for more on this strategy, see the video below )
(39,897)(0.0096)/198.76 ≈ (40,000)(0.01)/(200)
≈ (400)/(200)
≈ 2
Answer:

[39,897 x (96/10000)]/(19876/100) = [40,000 x 100]/[100 x 20,000] = 2

Approximating the given expression, we have:

(40,000 x 0.01)/200 = 400/200 = 2

Answer: C

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

:-) when we round 0.0096 ...aren't we getting 0.001 ? :)

if so then then 40000 * 0.001 = 40

so 40/200 = 0.2

why is the answer C ? :?

Yikes - I had a bad typo in there. Good catch. +1

Round .0096 to .01
(We look at only one digit to the right: .009 = .01)

Now, 40,000*.01 = 400
Better? :-)
