Imagine a question and stream-of-consciousness explanation for which this is the answer: 45
Question: 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?
Stream-of-consciousness: There are 60 goldfish because 15 / .25 = 60. 75% of the fish are below the surface because 100 - 25 = 75. There are 45 goldfish below the surface because 60 x .75 = 45.
