conversations.value: First find the total number of puppies: 8 puppies + 12 puppies = 20 puppies
  Then find the total number of puppies with spots: 3 puppies + 4 puppies = 7 puppies
  Then divide the number of spotted puppies by the total number of puppies and multiply by 100% to find the percentage of puppies with spots: 7 puppies / 20 puppies * 100% = 35%
