.000027 is the same as 2.7 x10^5 or 2.7E5 on a calculator, do the same for the .000009 = 9.0E6 and just plug in calculator

Answer 3

\[0.000027 = 2.7 \times 10^{-5}\]\[0.000009 = 9.0 \times 10^{-6}\]
\[\frac{ 0.000027 }{ 0.000009} = \frac{ 2.7 \times 10^{-5} }{ 9.0 \times 10^{-6} } = 0.3 \times 10^{-5+6} = 0.3 \times 10 = 3\]
