conversations.value: Darrell and Allen's ages are in the ratio of 7:11. If their total age now is 162, calculate Allen's age 10 years from now.
conversations.from: assistant
conversations.value: The total ratio representing their ages is 7+11= 18
  Since the fraction of the ratio that represents Allen's age is 11/18, Allen's current age is 11/18*162 = 99
  If Allen is currently 99 years old, in 10 years he will be 99+10 = 109 years old
