Answer 1

`((4.8*10^8))/((1.2*10^4))*(2.2*10^(-6))`

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

so

`\begin{gathered} (4.8*2.2)/(1.2)*(10^8*10^(-6))/(10^4) \\ \\ (4.8*2.2)/(1.2)*10^(8-6-4) \\ \\ (4.8*2.2)/(1.2)*10^(-2) \end{gathered}`

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

`\begin{gathered} (10.56)/(1.2)*10^(-2) \\ \\ 8.8*10^(-2) \\ =0.088 \end{gathered}`

so, the right option is B
