At a certain time of the day, Paolo, who is 6 feet tall, casts a shadow 9 feet long. If the tree beside him casts a shadow 12 feet long, how tall is the tree?

The proportions will be: 
6:9=_:12
  I
2:3

Find a number that when you pair it with 12, the answer will also be 2:3.
8:12 is equal to 2:3. So the answer is 8.

Cross Multiply
[tex] \frac{6}{9} [/tex]    [tex] \frac{x}{12} [/tex]

72 = 9x
[tex] \frac{72}{9} [/tex] = [tex] \frac{9x}{9} [/tex]

8 = x

8 feet = answer
