pets survey
what percent of the total students have a pet? round your answer to the nearest whole number percent.

Explanation:

Step1: Calculate the total number of students with pets

Add the number of students with pets in each grade: \(28 + 25+24=77\)

Step2: Calculate the total number of students

First, find the number of students in each grade:

• 6th grade: \(28 + 27=55\)
• 7th grade: \(25 + 27 = 52\)
• 8th grade: \(24+15 = 39\)

Then, sum them up: \(55+52 + 39=146\)

Step3: Calculate the percentage of students with pets

Use the formula \(\text{Percentage}=\frac{\text{Number of students with pets}}{\text{Total number of students}}\times100\%\)
\(\text{Percentage}=\frac{77}{146}\times 100\% \approx 52.74\%\)

Answer:

\(53\%\)
