How do you get 9 liters from a 10 and 7 liter beaker?
Fill the 7 beaker and pore contents into 10 beaker. Mark where the contents come up to on the 10 beaker. Fill the 10 beaker up and pour off the top of it into the 7 beaker until you are down to the mark. You will now have 3 litres in the 7 beaker. Mark where it comes up to. Empty the 10 beaker. Pour the 3 litres in the 7 litre beaker into the 10 litre beaker. Fill the 7 litre beaker up to the 3 litre mark and pore it into the 10 twice more. You now have 3*3=9 litres in the 10 litre beaker. QED.
