pump
 

People in England buy their petrol in litres but often talk about the previous measure of gallons.

Can you find out how many litres there are in one gallon?

 
 
 

When you've found out, let's suppose that I have to pay £1.00 for each litre.

 
 

I want to fill my 12 gallon petrol tank. How much will it cost me?

 
 
 
 
 
 
 

It would be good if you could talk to someone about how you worked this out and then please let us know too.
