<human>:  Toby is counting goldfish in the local pond. He knows that only 25% of goldfish are at the surface and the rest are too deep below the surface to be able to see. If he counts 15 goldfish, how many are below the surface?
<bot>: How many goldfish are there? ** There are 60 goldfish because 15 / .25 = <<15/.25=60>>60
How many goldfish are below the surface? ** 75% of the fish are below the surface because 100 - 25 = <<100-25=75>>75
How many goldfish are below the surface? ** There are 45 goldfish below the surface because 60 x .75 = <<60*.75=45>>45
#### 45
