Question

eva recorded the grade level and instrument of everyone in the middle school school of rock below.
school of rock
what percent of the 7th graders in the school of rock play drums? round your answer to the nearest whole number percent.

Explanation:

Step1: Identify the number of 7th - graders who play drums and total 7th - graders

From the table, the number of 7th - graders who play drums is \(14\), and the total number of 7th - graders is \(58\).

Step2: Use the percentage formula

The percentage formula is \(\text{Percentage}=\frac{\text{Part}}{\text{Whole}}\times100\%\). Here, the part is the number of 7th - graders who play drums (\(n = 14\)), and the whole is the total number of 7th - graders (\(N=58\)). So, \(\text{Percentage}=\frac{14}{58}\times 100\%\).
Calculate \(\frac{14}{58}\approx0.2414\). Then \(0.2414\times100\% = 24.14\%\).

Answer:

\(24\%\)
