12/7. You put the numbers into mixed numbers giving you 18/7 and 9/6. For division you flip the second fraction and multiply them together. So you do 18/7 x 6/9. You're also able to cross cancel 18 and 9 giving you 2/7 x 6/1. 6 x 2 is 12 and 7 x 1 is 7. Your answer is 12/7.

Answer:

32% of the students did not have a pet.

Step-by-step explanation:

From the total students (100%):

1/4 of them had a dog only, $\frac{1}{4}=0.25=25\%$ . Then, 25% had a dog only.
20% only had a cat.
15% had multiple pets.
0.08=8% only had other than cats or dogs.
<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.
The rest of the students $100\%-68\%=32\%$ , did not have any pet.
