Answer 2

Answer:

216 students passed the exam.

Step-by-step explanation:

To find the number of students who failed we must calculate 28% of 300 students (which means number of passed students) then subtract it from total Number of students to get the Number of students who passed.

Number of students who failed = 28/100 × 300 ( here 100 divides 300)

Therefore number of students who failed = 28 × 3

= 84 students failed the exam

So the number of students who passed = total number of students - number of students who failed

So the number of students who passed = 300 - 84 = 216 students Failed
