Answer: Choice D = 64%
Step-by-step explanation:
A ratio of 16:9 implies that, for every 16 females, there are 9 males
Total ratio = 16 + 9 = 25
This means, if you have 25 students, 16 will be females, while 9 will be males
Percentage of females = number of female/total number of students) x 100
Percentage of females = (16/25) x 100
= 64%
The percentage of females in the class = 64%
Choice D
