Question

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?

Answer 1

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.
