Please explain in detail

You could fill the 3 liter container with milk.
Then pour the milk into the 4 liter container, which contains now 3/4 liter milk.
Fill the 3 liter container again with milk.
Then pour again the milk into the 4 liter container, you can only pour 1 liter milk into the 4 liter container because it already contains 3/4 liter milk.
So in the 3 liter container is 2 liter of milk left.
