there are 55 6th graders and 85 8th graders at a middle school. of these students, 35 have dogs and 12 have cats. what is the percentage of people who have dogs

Answer 1

To calculate the percentage of people who have dogs, we first need to find the total number of students and the number of students who have dogs.

1. Total number of students: \[ \text{Total students} = 55 \text{ (6th graders)} + 85 \text{ (8th graders)} = 140 \]

2. Number of students who have dogs: \[ \text{Students with dogs} = 35 \]

3. Now, calculate the percentage of students who have dogs: \[ \text{Percentage of students with dogs} = \left( \frac{\text{Number of students with dogs}}{\text{Total number of students}} \right) \times 100 \] \[ \text{Percentage of students with dogs} = \left( \frac{35}{140} \right) \times 100 \] \[ \text{Percentage of students with dogs} = 0.25 \times 100 = 25% \]

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