A street sign's shadow is 16 feet long. Not far away, a metal barrel's shadow is 4 feet long. If the street sign is 12 feet tall, how tall is the metal barrel

Metal barrel = 3 feet tall

Step-by-step explanation:

street sign to shadow ratio: 12/16

metal barrel to shadow ratio:?/4

you can reduce 12/16 into 3/4 by dividing both numbers by 4.

that means that 12/16 is equal to 3/4. the street sign is 75% of its shadow, and the same would go for the metal barrel. hope thats not too confusing
