If the number of male students and female students in each of 3 classes is equal, and the average number of males in each class is 30, What is the total number of students in all 3 classes?
*My answer is 180, but I'm not sure.
you are correct.
If the males average 30/class, there are 90 males in 3 classes.
So, there are also 90 females.
To find the total number of students in all three classes, we need to determine the number of students in one class first.
Since the average number of males in each class is 30, and the number of male and female students in each class is equal, we can conclude that each class has 30 male students and 30 female students.
So, the total number of students in one class is 30 (male students) + 30 (female students) = 60 students.
To find the total number of students in all three classes, we multiply the number of students in one class by the number of classes:
60 students/class × 3 classes = 180 students.
Therefore, the total number of students in all three classes is 180. Your answer is correct.
To find the total number of students in all 3 classes, we need to determine the number of students in each class first.
We are given that the average number of male students in each class is 30. Since the number of male students and female students in each class is equal, we can infer that the average number of female students in each class is also 30.
To find the total number of students in each class, we add the number of male students to the number of female students. In this case, the total number of students in each class is 30 (males) + 30 (females) = 60.
Since we have 3 classes, we multiply the total number of students in each class (60) by the number of classes (3). Therefore, the total number of students in all 3 classes is 60 (students per class) x 3 (classes) = 180.
So, your answer of 180 is correct.
