Answer:
122.18 kilograms
Explanation:
A newborn panda weighs 1/5 pound, which is approximately 0.2 pounds. Since 1 pound is approximately 0.45 kilograms, the weight of one newborn panda in kilograms is 0.2 * 0.45 = 0.09 kilograms. If the mother panda has twins, the total weight of the twins is 2 * 0.09 = 0.18 kilograms.
The mother panda weighs 122 kilograms, so the total weight of the mother panda and her twins is approximately 122 + 0.18 = 122.18 kilograms, rounded to the nearest hundredth.
