First, add the number of total male and female students.
216 + 207 + 198 + 194 = 815 males
193 + 214 + 197 + 201 = 805 females
Second, add to find the total number of students.
815 + 805 = 1620
Third, create a ratio from females to total students
805/1620
Fourth, simplify the fraction.
805/1620 → 161/324
Therefore, the answer is A.
Best of Luck!
