conversations.value: Can you break down the solution for me for this math problem: One-third of a class of 39 students took part in a math competition. How many students did not participate in the competition?
conversations.from: assistant
conversations.value: Since one-third of the class participated, there are 39 * 1/3 = 13 students who participated in the competition.
  This means that 39 – 13 = 26 students did not participate.
