Suppose a model of the space shuttle "Endeavour" is 10 inches tall. The actual height of the "Endeavour" is 100 feet. What is the scale of the model?

100 feet = 1200 inches
scale = 10 inches : 1200 inches
1 inch : 120 inches 
Set up a ratio.
10 : 100 = 10/100 = 1/10
The model is 1/10 the size of the Endeavour. 
Ignore my answer.
I did not notice that one measurement is in feet.
I compared inches to feet, which you cannot do.
