First I would convert the. 85 into an 85%

Now you have 85% like math and 15% like science.

Since there are 60 students, you then take. 85*60=51 students who prefer math and. 15*60=9 students who prefer science.

Then you take math (51) minus science (9)

51-9=42 more students prefer math over science
