Final answer:
To convert 5 lb 12 oz to kilograms, multiply 5 lb by 0.45 to get the equivalent in kilograms. Then, divide 12 oz by 16 to get the equivalent in pounds and multiply it by 0.45 to get the equivalent in kilograms. Add the two results to get the final answer in kilograms, which is approximately 2.6 kg.
Step-by-step explanation:
To convert 5 lb 12 oz to kilograms, we first need to convert 5 lb to kilograms. We know that 1 pound is approximately 0.45 kilograms. So, 5 lb is approximately 5 * 0.45 = 2.25 kg. Next, we need to convert 12 oz to kilograms. Since 1 pound is equal to 16 ounces, we can divide 12 oz by 16 to get the equivalent in pounds: 12 / 16 = 0.75 lb. Similar to before, we can multiply 0.75 lb by 0.45 to get the equivalent in kilograms: 0.75 * 0.45 = 0.3375 kg. Finally, we add the two results together: 2.25 kg + 0.3375 kg = 2.5875 kg. Rounding to the nearest tenth gives us 2.6 kg.
