relationship operator

Hi there,

I have come across a notation that I cannot break, I hope you might help me

The notation is Pg:Pcr:Pm=1:S:1-s

I know that they are that one term is directly proportional to other how would I write in other way, maybe more meaningful?

It looks to me like a ratio

$\displaystyle P_g : P_{cr} : P_m = 1 : S : 1-S$

The total = $\displaystyle 1 + S + (1-S) = 2$

So let's say, just for example, that you have £200 to share among $\displaystyle P_g$, $\displaystyle P_{cr}$ and $\displaystyle P_m$. In this case:

$\displaystyle P_g$ gets £100
$\displaystyle P_{cr}$ gets some amount between 0 and £100 depending on what $\displaystyle S$ is.
$\displaystyle P_m$ gets the rest.

Note that this is assuming $\displaystyle S$ is less than 1 so that $\displaystyle 1-S$ is positive. It depends on the situation you are looking at.
