Lets say I have 5 casino gamblers, they all account for 1500 chips. They each got 724 (48.2%), 182 (12.1%), 314 (20.9%), 72 (4.8%), and 209 (13.9%) chips respectively. If the one with 724 (48.2%) chips wanted to give away his chips to the other 4, not in 4 equal parts but respectively to the % they each got, how can I divide the 48.2% based on the % they already have? In a way that the one with 314 (20.9%) gets more, and the one with 72 (4.8%) gets less, but all tied to that initial percentage.
Edit: A comment on the downvote would be helpful.
You can scale up their chip numbers or percentages. The player who started with $182$ should have $\frac {182}{182+314+72+209}=\frac {182}{777}\approx 23.42\%$ of the total. They will now have $\frac {182}{777}(724+777)\approx 352$ chips of which $170$ are from the new batch.
