Exchange rates questions and answers

An exchange rate like £1 = $1.25 tells you how much of one currency you get for another. Converting is direct proportion: to go from pounds to dollars, multiply by 1.25; to go from dollars to pounds, divide by 1.25. Check your answer makes sense: you should get more of the "cheaper" currency.
