Change the following sentence into a passive voice

The dog showed no interest

no interest was showed the dog

To change the sentence "The dog showed no interest" into passive voice, you can follow these steps:

1. Identify the subject, verb, and object in the sentence.
- Subject: The dog
- Verb: showed
- Object: no interest

2. Flip the positions of the subject and object.
- The object ("no interest") becomes the subject.
- The subject ("the dog") becomes the object.

3. Add a form of the verb "to be" in the appropriate tense.
- Since the original sentence uses the past tense, we can use the past tense form of "to be," which is "was."

Applying these steps, the sentence in passive voice would be:
"No interest was shown by the dog."
