conversations.value: I need help with this problem:
  Omi is twice as old as Kimiko. Arlette is 3/4 times as old as Kimiko. If Kimiko is 28 years old, calculate the average age of the three?
conversations.from: assistant
conversations.value: If Kimiko is 28, Omi is 2 * 28 years = 56 years old.
  Arlette is 3/4 * 28 years = 21 years old.
  If you add up their ages, it sums to 21 years + 56 years + 28 years = 105 years
  The average age for the three is 105 years / 3 people = 35 years/person
