Final answer:
The ratio of 2 males for every 4 females, with 7 males present, leads us to calculate that there are 14 females. Adding males and females gives a total of 21 students.
Step-by-step explanation:
The question asks us to determine the total number of students based on the given ratio of females to males and the known quantity of males. In the given scenario, the ratio is 2 males for every 4 females. If there are 7 males in total, we can calculate the number of females by setting up a proportion where 2 males correspond to 4 females:
- 2 males / 4 females = 7 males / x females
- x = (4 females / 2 males) * 7 males
- x = (2 females / 1 male) * 7 males
- x = 2 * 7 = 14 females
To find the total number of students, we add the number of males and females:
Total students = 7 males + 14 females = 21 students
