Film 4: Percentages: Books, Wastewater, Chickens and Elections (14'37")
This film shows how percentages are useful in a succession of situations: designing a robust wastewater treatment plant, working out the value of discounts in a book shop, voting margins in an election and rating the return on investment on machinery in a chicken processing plant.
