I am not quite sure that you have grasped the issue.........

Explanation:

In a gaseous mixture, the partial pressure, $P_{1}$ $P_1$ , exerted by a component gas is the same as the pressure it would exert if it alone occupied the containers. The total pressure, $P_{total}$ $P_"total"$ is the sum of the individual partial pressures.

$P_"total"=P_1+P_2+..........P_n$

But if we use the Ideal Gas Equation:

$P_"total"=(n_"total"RT)/V$

$=(RT)/V{n_1+n_2+.....................+n_n}$

And the partial pressure of a component gas is thus simply,

$n_i/{n_1+n_2+.....................n_n}xxP_"total"$

If I have missed the direction of your question, please qualify it.
