A newborn panda weighs only one pound. If the mother panda weighs 122 kilograms and has twins, approximately how many kilograms do they weigh in total? Use the approximation that 1 pound is equal to 0.45 kg. Round your answer to the nearest hundredth.

Answer :

Final answer:

The total weight of the mother panda and her two newborn cubs, given that each cub weighs about a pound (equivalent to 0.45 kg), is approximately 122.9 kilograms.

Explanation:

The question involves conversion from pound to kilograms. In the problem, it is given that 1 pound is approximately 0.45 kilograms. Newborn pandas are said to weigh only 1 pound, which would equate to 0.45 kilograms.

Since the mother panda gave birth to twins, the combined weight of the twins would be 0.45 kg * 2, which equals 0.90 kg, rounded to the nearest hundredth. So, the total weight of the mother panda and her newborn twins would be 122 kg (the weight of the mother) + 0.90 kg (the weight of the twins). That makes the total approximately 122.9 kg.
