Calculating the Number of Students Learning Piano and Violin

To calculate the number of students learning piano and violin, we can use the given percentages and the total number of students in the school.

Given: - 52% of all students learn to play the piano - 28% learn to play the violin - Total number of students in the school is 250

Calculations

1. Number of Students Learning Piano: - Percentage of students learning piano: 52% - Total number of students: 250 - Calculation: \( 250 \times \frac{52}{100} = 130 \) students

2. Number of Students Learning Violin: - Percentage of students learning violin: 28% - Total number of students: 250 - Calculation: \( 250 \times \frac{28}{100} = 70 \) students

Therefore, there are 130 students learning piano and 70 students learning violin in the school.

Answer
