Question 287115
 Mary drew a model of her school, 
the length of the school is 27ft 
and the width is 84ft. 
--------------------------------------------
The model's width is 3ft and the length is "x". 
------------------------------------------------
What length in feet, is x?
model length/length = model width/width
-------------------------------------------
x/27 = 3/84
--------
x = 27(3/84)
---
x = 81/84 = 0.96 ft
=================================
