Explanation:

Step1: Find total 6th graders

Sum 6th grade instrument counts: \(17 + 12 + 10 + 18 = 57\)

Step2: Calculate keyboard percentage

Divide keyboard count (18) by total (57), multiply by 100: \(\frac{18}{57} \times 100 \approx 31.58\)

Step3: Round to nearest whole number

\(31.58 \approx 32\)

Answer:

32%
