Question

Celina surveyed 60 students at her school and found that 0.75 of the students she surveyed said their favorite class is math. Another 35% of the students she surveyed reported that their favorite class is science. How many more students in the survey prefer math over science?

Answer 1

0,75⇔75% (m)

35% (s)

75%+35%=110%

110%-100%=10% (m+s)

75%-10%=65% (only m)

60-100%

(?)-65%

65*60:100=39 (stud.)
