Volume of milk available = 9/12 of a container

Volume of milk poured in a pan = 2/3 of a container

Quantity of milk left = Initial quantity of milk less the quantity poured out

That is 9/12-2/3 = 1/12 of the container of milk

This means that there will be only 1/12 of the container of milk left
