conversations.value: I need a clearer understanding of how to solve: To let Ruth know how long her fish will live, her father tells her that well-cared fish can live 2 years longer than dogs live. On average, dogs live 4 times as long as hamsters live. And hamsters live an average of 2.5 years. How long can a fish live?

conversations.value: Knowing that dogs live 4 times the age of hamsters, dogs live 4 * 2.5 = 10 years.
  If Ruth takes care of the fish, it can live 10 + 2 = 12 years.
