You are making band posters for your band's upcoming show. You have put up a few posters that are 24 inches by 16 inches around town, but the managers at the venue told you that the largest poster size they allow inside the building is 20 inches by 12.8 inches. How much will you have to reduce your poster for it to be the right size to hang up in the building?
