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?

• Algebra -

100 feet = 1200 inches

scale = 10 inches : 1200 inches

1 inch : 120 inches

• Algebra -

Set up a ratio.

10 : 100 = 10/100 = 1/10

The model is 1/10 the size of the Endeavour.
