# 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%.
