conversations.from: assistant
conversations.value: There are 12 + 12 = 24 students in Miss Albert's class.
  12 x 1/3 = 4 girls are on varsity.
  12 x 1/4 = 3 boys are on varsity.
  A total of 4 + 3 = 7 students in Miss Albert's class are on varsity.
  Therefore, 24 - 7 = 17 students are not on varsity.
