To find the total number of females in grades 11 and 12, we add the number of females in grade 11 (50) to the number of females in grade 12 (61): 50 + 61 = 111.
Next, we find the total number of females across all grades by adding the numbers of females in each grade: 31 + 42 + 50 + 61 = 184.
To find the percentage of females in grades 11 and 12, we divide the total number of females in grades 11 and 12 (111) by the total number of females across all grades (184) and then multiply by 100 to get a percentage: (111 / 184) * 100 = 60.33, which rounds to 60%.
Therefore, 60% of females are in grades 11 and 12.
