Answer 3

The question is about the number of spines in the dorsal fins of three fish: the golden perch, the stingray, and the sea mouse. The total number of spines is 40, and the stingray has 20 spines. The sea mouse has 16 spines less than the stingray. How many spines does the golden perch have?

To answer this question, we can use the following steps:

- Subtract 16 from 20 to get the number of spines of the sea mouse: 20 - 16 = 4. - Add the number of spines of the stingray and the sea mouse to get the total number of spines of these two fish: 20 + 4 = 24. - Subtract the total number of spines of the stingray and the sea mouse from 40 to get the number of spines of the golden perch: 40 - 24 = 16.

Therefore, the answer is 16. The golden perch has 16 spines in its dorsal fin.
