A student made a model of a building. The model was 3 feet high and 12 feet wide. The building is 720 feet wide. Which proportion correctly show how to find the height of the building?
Ok, so what we do is simply divide 720 by 12 720/12=60 next you just multiply whatever part of the building by 60 in order to get a correct proportion in this case we are doing 60*3=180 and the answer is the height of the building must be 180 feet.
