Step-by-step reasoning process: There were 50 x 3 = 150 tadpoles. There are 50 - 7 = 43 fish left in the pond. There are 150 / 2 = 75 tadpoles left in the pond. There are 75 - 43 = 32 more tadpoles than fish in the pond now.
The question and answer:
Question and answer: There were 50 fish in a pond and 3 times as many tadpoles. If Curtis catches 7 fish and half the tadpoles develop into frogs, how many more tadpoles than fish are there in the pond now?
The answer is 32
