### Instruction:
Nadia is learning to play the piano. She normally makes 3 mistakes per 40 notes and can play about 60 notes a minute.   If she plays for 8 minutes how many mistakes will she make on average?

### Response:
 เธอเล่นเปียโนได้ 480 โน้ตเพราะ 8 x 60 = <<8*60=480>>480
นี้คือ 12 กลุ่มของ 40 โน้ตเพราะ 480/40 =<<480/40=12>>12
เธอทำผิด 36 ครั้งเพราะ 12 x 3 = 36
