DeSTRESS films combine live-action explanation and interviews, filmed in a variety of locations, with narrated animations that take the viewer through a worked example. 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.
