Answer 1

$\frac{(4.8\times10^8)}{(1.2\times10^4)}\times(2.2\times10^{-6})$

first we can separate the values ​​with exponents that having the same base can be reduced

so

$\begin{gathered} \frac{4.8\times2.2}{1.2}\times\frac{10^8\times10^{-6}}{10^4} \\ \\ \frac{4.8\times2.2}{1.2}\times10^{8-6-4} \\ \\ \frac{4.8\times2.2}{1.2}\times10^{-2} \end{gathered}$

now do the multiplication between 4.8 and 2.2 and reduce the fraction

$\begin{gathered} \frac{10.56}{1.2}\times10^{-2} \\ \\ 8.8\times10^{-2} \\ =0.088 \end{gathered}$

so, the right option is B
