Which weighs more: a watermelon that weighs 7.5 kilograms or a baby that weighs 12 pounds?

• Watermelon

• Baby

To compare the weights, convert 12 pounds to kilograms: 12 pounds is approximately 5.44 kilograms. Since 7.5 kilograms (watermelon) is greater than 5.44 kilograms (baby), the correct answer is that the baby weighs less.
