Answer: it is easiest if you first find the percent of people present.  To do this, divide 1200/1500.  This equals 80%.  If there is 80% of students present, there needs to be 20% of students absent because it is out of 100% of students

Answer:

20%

Explanation:

Total number of students = 1500

Number of students present = 1200

Number of students absent = Total number of students - number of students present

Number of students absent = 1500 - 1200 =300

%number of students absent = 300 / 1500 * 100 = 20%
