No: of students who can dance = (20/100)*125 = 25
No: of students who sings = (2/5)*125 = 50
No: of students good at sports = (2/5) * (125-25-50) =20
Ratio of students who can dance to that of sports = 25:20 = 5:4

***
20%*125=25=students can dance
2/5*125=50=students can dance
ratio of the number of students who can dance to the number of students who are good at sports? 25/50=1/2
