Trying to understand if a total changes but the amount does not change, how does this affect the percentage of that total?? Example: A 2.5 gallon container is half full (50%) and you then pour the contents into a 2 gallon container.... Or a 3 gallon container, etc.. Based upon percentage, how full is the new container??? I appreciate the help in understanding this....
