conversations.value: Provide a step by step solution for the following math problem: Eden's mom is twice as old as Eden, who is twice as old as Devin. If Devin is 12 years old, what's the average age of the three?
conversations.from: assistant
conversations.value: If Devin is 12 years old, then Eden is 2 * 12 years = 24 years old.
  Since Eden's mom two times older than Eden, her age is 24 years * 2 = 48 years.
  In total, they have 48 years + 24 years + 12 years = 84 years
  The average age for the three is 84 years / 3 people = 28 years/person
