A Fishy problem

A Fishy problem

In class we were doing  problem solving

Milly just got a new pet fish. The pet shop owner told her that she needs to put the fish into exactly one litre of water. The problem is she can only find two containers. One container holds 7 litres and the other container holds 4 litres of water.

Can you use these two containers to put exactly one litre of water into the fish tank?

The answer is yes. Because you fill the 4 litre container and you pour it into the 7 litre container. Now  the seven litre container  can only hold 3 litres of water because 4 + 3 = 7. Now I filled the 4 litre container again. Then I poured it  into the seven litre container until it got filled to the top. Now I was left with 1 litre in the four litre container.  Now Millie can pour the 1 litre of water from the container into the fish tank.
