If 5 identical components weigh 20 kg, what is the weight of one component?
4 kg
The five components are identical, so the total weight is shared equally among them and the weight of one is the total divided by the count.
This is a direct division of a whole into equal parts.
Weight of one component \(=\dfrac{20\ \text{kg}}{5}=4\ \text{kg}\).
As a check, multiplying back gives \(5\times4=20\ \text{kg}\), which matches the given total.
Options such as 2 kg or 10 kg come from dividing or multiplying by the wrong number, and 5 kg would need a total of 25 kg.
Hence, the answer is 4 kg.
