On a math test 12 students earned an a this number is exactly 25% of the total number of students in the class how many students are in the class

48 students.

Step-by-step explanation:

25% of total students = 12

suppose,

total students = x

so,

25% of x=12

(25/100) * x=12

25*x = (12*100)

x=1200/25

x=48

therefore,

x = total students = 48.
