ratio and proportion.
Another question I am stumped on. An explanation would be appreciated.
Public swimming pools require 3 parts chlorine liquid and 2 parts salt water to every 100 parts water to kill bacteria. How much chlorine liquid is required in a 4000L pool?
3 parts chlorine in a 105 part solution.
The fraction of chlorine liquid is
The chlorine amount in 4000L is the chlorine liquid fraction of that.
ok I got it now, I was using 3/100 rather than 3 /105. Thanks!
