conversations.value: A roll of 25 m wire weighs 5 kg. How much does a 75 m roll weigh?
conversations.from: assistant
conversations.value: We know that the 75 m roll is three times bigger than the 25 m roll because 75 m / 25 m = 3
  This means the 75 m roll weighs 3 times more than the 25 m roll: 5 kg * 3 = 15 Kg
