A patient weighs 180 pounds. Approximately how many kilograms is this?

Explanation:
When converting pounds to kilograms, use the approximate factor 1 kg ≈ 2.2046 lb. So kilograms = pounds ÷ 2.2046. For 180 pounds: 180 ÷ 2.2046 ≈ 81.6 kg. Rounding to one decimal gives about 81.6 kg, which is very close to 81.8 kg, the closest option. The other values correspond to weights around 158 lb (72 kg), 132 lb (60 kg), and 198 lb (90 kg), which are farther from 180 lb. So the best choice is about 81.8 kg.
