conversations.value: Each dog consumes 250 grams x 2 = 500 grams of dog food each day.
  So, 4 dogs consume 500 grams x 4 = 2000 grams of dog food each day.
  Since there are 1000 grams in 1 kilogram, then the 4 dogs can consume 2000/1000 = 2 kilograms of dog food each day.
  Aunt Gemma bought a total of 50 kilograms x 2 = 100 kilograms of dog food.
  Hence, it will last 100 kilograms/2 kilograms = 50 days.
