The state capitol building in Baton Rouge, Louisiana, is 450 feet tall. Ella’s scale model of the building uses the scale 25 feet = 10 inches. How tall is Ella’s model?
For this case what we can do to represent this problem is the following rule of three: 25 feet ---> 10 inches 450 feet ---> x Clearing the value of x we have: x = (450/25) * (10) x = 180 inches. Now, let's convert this value to feet: x = 180 * (1/12) = 15 feet Answer: Ella's model is 15 feet tall
