The Sears Tower in Chicago is 1,450 feet tall. A model of the tower is 24 inches tall. What is the ratio of the height of the model to the height of the actual Sears Tower?

To find the ratio, we need to first convert the heights to the same unit.

1,450 feet = 1,450 * 12 = 17,400 inches

Now, the ratio of the height of the model to the height of the actual Sears Tower is:

24 inches (model) : 17,400 inches (Sears Tower)

Simplifying this ratio gives:

1 : 725
