    In the UK, petrol cost £1.24 per litre
    In the USA, petrol cost 3.15 dollars per US gallon

    1 US gallon = 3.79 litres
    £1 = 1.47 dollars

    Was petrol cheaper in the UK or in the USA?

    Okay, so convert everything into the same units. Let's convert everything into litres and pounds.

    UK: 1 litre is 1.24 quid.
    US: 3.79 litres is 3.15 dollars

    This is the same as saying 1 L = \frac{3.15 \$}{3.79} = 0.831 \$, you agree?

    So let's look at what we have so far:

    UK: 1 litre is 1.24 quid
    US: 1 litre is 0.831 dollars

    How much is 0.831 dollars in pounds? We know that 1.47 \$ = 1 £ so 1 \$ = \frac{1}{1.47} £

    Now how much is 0.831 $ in terms of pounds and what does that let you say about the relative costs?

    P.S: Moved to maths.
