Answer:

32% of the students did not have a pet.

Step-by-step explanation:

From the total students (100%):

  1. 1/4 of them had a dog only, \frac{1}{4}=0.25=25\%. Then, 25% had a dog only.
  2. 20% only had a cat.
  3. 15% had multiple pets.
  4. 0.08=8% only had other than cats or dogs.
  5. <u>Adding up all these cases, we obtain the proportion of students that had at least one pet:</u> 25\%+20\%+15\%+8\%=68\%. Then, 68% of the students did have a pet.
  6. The rest of the students 100\%-68\%=32\%, did not have any pet.
