there are 20 male students taking a class, if 40% of the students are males then how many students are in the class?

(please show how you did it and answer)

Let x = total students

0.4x = 20

x = 20/0.4
x = 50

what is N*.40=20

solve for N

To find the total number of students in the class, we need to use the percentage given and the number of male students.

First, we can calculate the total number of students by dividing the number of male students by the percentage of male students in decimal form (40% = 0.4).

Number of male students = 20
Percentage of male students = 40% = 0.4

Total number of students = Number of male students / Percentage of male students
Total number of students = 20 / 0.4 = 50

Therefore, there are 50 students in the class.
