An old house in Boxerville measures 30 feet in height and has windows 5-feet in width. An architecture student builds a proportional model that is 3-feet high. How wide are the model's windows, in feet?
terenzreignz (terenzreignz):
Original height was 30 feet, in the model, 3 feet.
What did you multiply to 30 so that you get 3?

Usually it's your job to simplify.
But you can drop the zeros at both the numerator and denominator.
