Say I have this term

$\displaystyle \frac{0.5}{s+2}$ ,

could I just say that 0.5 is a constant so it can be written as

$\displaystyle 0.5\cdot\frac{1}{s+2}$

and transform it normally, which would then be

$\displaystyle 0.5\cdot\exp^{-2t}$

or am I just being plain stupid and should know that things like this arent allowed with laplace terms?

I have been looking at examples, just cant seem to find any that would answer me :(
