On a math test, 60%of students use a pencil, half of the remaining students used a red pen if 6 students use a red pen, how many students are in the class

30 people are in the class

Hi!

If 60% of the students used a pencil, then the remaining percentage of the class is 40%, as 60% + 40% = 100%. Since half of that remaining percentage, or half of 40%, used a red pen, then that means 20% used a red pen.

Since 6 students used a red pen, and that is 20%, that means 6 is 20% of the total students in the class.

To get 100%, just multiply both by 5, and you get 30 for 100% of the students.

Therefore, there are 30 students in the class.

Hope this helped!
