Denise measured a community college and made a scale drawing. In real life, a building at the college is 122 meters long. It is 183 centimeters long in the drawing. What scale did Denise use?
3 centimeters : meters
To find the scale, we can divide the length of the building in the drawing by the actual length of the building.
Scale = Length in drawing / Length in real life = 183 centimeters / 122 meters = 1.5 centimeters : 1 meter
Therefore, Denise used a scale of 1.5 centimeters : 1 meter.
