type of animal	koala	jaguar	anteater	gorilla	penguin

Explanation:

Step1: Recall percentage formula

The formula for percentage is $\text{Percentage}=\frac{\text{Number of favorable cases}}{\text{Total number of cases}}\times100\%$. Here, the total number of zoo - attendees is $192 + 240+608 + 384+176=1600$.

Step2: Calculate percentage for Penguin

For Penguin, $\text{Percentage}=\frac{192}{1600}\times100\% = 12\%$.

Step3: Calculate percentage for Gorilla

For Gorilla, $\text{Percentage}=\frac{240}{1600}\times100\%=15\%$.

Step4: Calculate percentage for Anteater

For Anteater, $\text{Percentage}=\frac{608}{1600}\times100\% = 38\%$.

Step5: Calculate percentage for Jaguar

For Jaguar, $\text{Percentage}=\frac{384}{1600}\times100\%=24\%$.

Step6: Calculate percentage for Koala

For Koala, $\text{Percentage}=\frac{176}{1600}\times100\% = 11\%$.

Answer:

Type of animal	Percentage
Gorilla	15%
Anteater	38%
Jaguar	24%
Koala	11%
