how many kilograms are there in 4 pounds? hint: 1 lb ≈ 0.454 kg round your answer to the nearest tenth.
Answer
Explanation:
Step1: Set up conversion
We know 1 lb ≈ 0.454 kg, for 4 pounds, we multiply by the conversion - factor. $4\times0.454$
Step2: Calculate the result
$4\times0.454 = 1.816$
Step3: Round to the nearest tenth
Looking at the hundredth - digit (1), since 1 < 5, we keep the tenth - digit as it is. So 1.816 rounds to 1.8.
Answer:
1.8
