Answer:
The sentence "The cat ate the fish" is in the active voice. To change it to the passive voice, we need to make the object of the active sentence the subject of the passive sentence, and the subject of the active sentence the object of the passive sentence.
Here is the passive voice version of the sentence:
The fish was eaten by the cat.
In this sentence, "the fish" (the object of the active sentence) becomes the subject of the passive sentence, and "the cat" (the subject of the active sentence) becomes the object of the passive sentence. The verb "ate" changes to "was eaten" to match the passive voice.
