Question

andy, who just won the election for student body president at yardley middle school, tallied how many votes he received from each grade. what percent of his votes were from the sixth grade or eighth grade? write your answer using a percent sign (%).

Explanation:

Step1: Find the number of votes from each grade

From the bar - graph:

• Sixth - grade votes: \(600\)
• Seventh - grade votes: \(300\)
• Eighth - grade votes: \(300\)

Step2: Calculate the total number of votes

Total votes \(=600 + 300+300=1200\)

Step3: Calculate the number of votes from sixth or eighth grade

Votes from sixth or eighth grade \(=600 + 300=900\)

Step4: Calculate the percentage

The formula for percentage is \(\text{Percentage}=\frac{\text{Part}}{\text{Whole}}\times100\%\)
Here, the part is the number of votes from sixth or eighth grade (\(900\)), and the whole is the total number of votes (\(1200\))
\(\text{Percentage}=\frac{900}{1200}\times 100\%=\frac{3}{4}\times100\% = 75\%\)

Answer:

\(75\%\)
