answer

Explanation:

Step1: Identify relevant values

From the table, total students with pets = 79, total students = 138.

Step2: Calculate percentage

Percentage = $\frac{\text{Students with pets}}{\text{Total students}} \times 100$ = $\frac{79}{138} \times 100$
Calculate $\frac{79}{138} \approx 0.57246$
Multiply by 100: $0.57246 \times 100 \approx 57.246$

Step3: Round to nearest whole number

57.246 rounded to nearest whole number is 57.

Answer:

57%
