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?
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.
