Question: The central Texas countryside contains many toads that come out at night.  For every green toad, there are 25 brown toads, and one-quarter of the brown toads are spotted.  If there are 50 spotted brown toads per acre, how many green toads are there per acre? Is final answer 8?
Answer: If there are 50 spotted brown toads per acre, and this represents one-quarter of the brown toads, then there are 50*4=<<50*4=200>>200 brown toads per acre.
If for every 25 brown toads there is one green toad, then there are 200/25=<<200/25=8>>8 green toads per acre.
#### 8
