"If 3 liters of water are added to the bucket when it is half full of water, the amount of water in the bucket will increase by 1/3"

How does that translate into a mathematical formula? What would be the solution?

Thanks for your help!

Let's call the capacity "c" here.
We have c/2 to start with (half full of water)
Add 3 liters to this:
c/2 + 3
and we have one and one third what we had before --
1 1/3 is 4/3, so
c/2 + 3 = (4/3)(c/2)
