conversations.value: The total ratio representing the age of the three siblings is 4+3+7 = 14
  Halima's age is represented by the fraction 4/14, which means she is 4/14*126 = 36 years old.
  Beckhams age, from the total age of the three, is 3/14*126 = 27
  The difference in age between Halima and Beckham is 36-27 = 9
