Answer:6000
Step-by-step explanation:3 quarters is equal to 9/12. And 1/3 is equal to 4/12
If it is 9/12 full and 2500 gallons are drained then there are 4/3 left
9/12 - 4/3 is equal to 5/12.
Thta means 2500 gallons is 5/12 of the whole container
5/12 divided by 5 is 1/12
And 2500 divided by 5 is 500
That means every 1/12 of the container can fill 500 gallons
Do then 500 times 12 is 6000
Sorry I am really bad at explaining
