Question

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?

Answer 1

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
