A college professor teaches a class of 80 students. Fourteen students are business majors, six are education majors and the rest are undecided. What percentage of the class is undecided?
Given :
Total number of students in the class $= 80$
Number of students from business majors $=14$
Number of students from education majors $=6$
To do :
We have to find the percentage of the class that is undecided.
Solution :
$Number of students undecided =$
$\Rightarrow Number of students in the class - (Number of students in business majors + Number of students in education majors)$
$Number of students undecided = 80 - (14 + 6)$
$ = 80 - 20$
$ = 60$
$Undecided percentage in class = \frac{Number of students undecided}{Total number of students in class}\times 100$
$ = \frac{60}{80} \times 100$
$= \frac{6}{8} \times 100$
$= \frac{3}{4} \times 100$
$ = 3 \times 25$
$ = 75$%
Therefore, the percentage of class undecided is 75%.
