\(0.045*1.9 ≈ 0.1\)

\(0,03*0,005*0,1 = 0.000015 = 15^{-6}\)

\(\frac{0.1}{15^{-6}} ≈ 5,700\)

You don't need to know the exact value, but only the correct decimal place (you can note that the answer choices change only in the decimal places).

Since the answer choices are very spread apart, we can be very aggressive with our estimation

\(\frac{0.045\times1.9}{0.03\times0.005\times0.1} ≈\frac{0.05\times2}{0.03\times0.005\times0.1} \)

\( ≈\frac{0.05\times2}{0.03\times0.005\times0.1} \)

\( ≈\frac{0.1}{0.03\times0.005\times0.1} \)

\( ≈\frac{1}{0.03 \times 0.005} \)

\( ≈\frac{1}{0.00015} \)

\( ≈\frac{1}{0.0002} \) close enough!

\( ≈\frac{10,000}{2} \)

\( ≈5000\)

The closest answer choice is A

Cheers,
Brent

Multiply by 1000/1000 to make them all integers. Then the answer you receive multiply that by 1000 and that is your final answer.­­­
