conversations.value: I'm completely lost with this math problem: In a certain school, two classes have a total of 80 students. Each class has the same amount of students, and in each class 40% of the students are girls. How many boys are in each class?
  Can you give me a hand?

conversations.value: If both classes have the same amount of students, that means each of them has 80 / 2 = 40 students.
  The girls in each class make up to 40%, so there are 40/100 * 40 = 16 girls in each of them.
  That means the rest of the class are boys, so there are 40 - 16 = 24 boys in each class.
