2/5
2/5 of 40 choose flute=16
8 choose drum
16+8=24, 40-24=16(it means rest 16 students chooses piano and fraction of 16 is 2/5)
Fraction of students having drums choice is 1/5 (8/40)
2/5 of 40 choose flute=16
8 choose drum
16+8=24, 40-24=16(it means rest 16 students chooses piano and fraction of 16 is 2/5)
Fraction of students having drums choice is 1/5 (8/40)

Answer:
Total =40 students
2/5 of 40 = flute
2/5*40= flute
16 =flute
8= drum
40-(16+8) = piano
40 - 24= piano
16= piano
Fraction for flute = 2/5
Fraction for piano = 2/5
Fraction for drum = 5/5 - (2/5+2/5)
= 5/5-4/5
=1/5
