14% of 60%=14×60/100=⅗×14=42/5=8.4%.
For simplification purposes let the number of students in the college=1000.
60% play sports=600 students.
14 out of every 100 of sports students play baseball, that is, 84 students play baseball.
Since there are 1000 college students 84/1000=0.084 play baseball, 0.084 is 8.4%.
