Answer:
2064 g, 21.3 lb, 452 oz, 16.7 kg
Step-by-step explanation:
Let's change all units to grams to be able to compare the amounts.
21.3 lb * 454 g / lb = 9,670.2 g
2064 g = 2064 g
16.7 kg * 1000 g / kg = 16,700 g
452 oz * 1 lb / 16 oz * 454 g / lb = 12,825.5 g
From least to greatest:
2064 g, 21.3 lb, 452 oz, 16.7 kg
