1 answer

To find the percentage of students who have dogs, we need to first determine how many students have dogs out of the total number of students in the middle school.

  1. Determine the total number of students:

    • Number of 6th graders: 55
    • Number of 8th graders: 85
    • Total students = 55 + 85 = 140
  2. Identify the number of students who have dogs:

    • According to the information provided, 35 students have dogs.
  3. Calculate the percentage of students who have dogs:

    • The formula for calculating the percentage is: \[ \text{Percentage} = \left( \frac{\text{Number of students with dogs}}{\text{Total number of students}} \right) \times 100 \]
    • Plugging in the numbers: \[ \text{Percentage} = \left( \frac{35}{140} \right) \times 100 \]
  4. Perform the division:

    • \( \frac{35}{140} = 0.25 \)
  5. Convert to percentage:

    • \( 0.25 \times 100 = 25% \)

Thus, the percentage of students who have dogs is 25%.
