Question

Three students failed their last test. If 12% of the class failed, how many students are in the class?

Answer 1

Answer:

25 students.

Step-by-step explanation:

12% is 3 students.

100% is the number of students in the class.

3 times 100 divided by 12 is 25.

So there are 25 students in the class.

Answer 2

Answer:

There are 25 students in the class.

Step-by-step explanation:

Let x be the number of students in the class

12% failed and the number of students is 3

x*12% = 3

x*.12 = 3

Divide each side by .12

x * .12 /.12 = 3/.12

x =25

There are 25 students in the class
