The ratio between the height of the model to the height of the actual sears tower is 1 : 725.
The sears tower in Chicago is 1450 feet high.
A model of the tower is 24 inches tall.
We need to determine the ratio of the height of the model to the height of the actual sears tower.
Now,
The height of tower is given in feet and the height of a model of a tower is given in inches. We need to change the unit inches into feet to determine the ratio.
Therefore,
We know that 1 inches is equal to 0.083 feet.
Thus,
The height of a model of a tower in feet is 1.992 that is rounded off to 2.
[tex]\begin{aligned}\rm{Ratio}&=\dfrac{2}{1450}\\&=1:725 \end{aligned}[/tex]
Thus, the ratio between the height of the model to the height of the actual sears tower is 1 : 725.
