Question

How do you convert 43 hectometres to kilometre?

Answer 1

Hint: We first find the relation between hectometre and kilometre. The measurement is common in measurement units. We find the relation as 1 hectometre being equal to $0.1$ kilometre. We use the unitary system, to find the length of the 43 hectometres in kilometre.

Complete step-by-step answer:
We need to convert the length by changing its unit from hectometre to kilometre.
We find the relation between hectometre and kilometre 1 hectometre being equal to $0.1$ kilometre.
We already have that in the unitary system. The unitary method is a method in which we find the value of a unit and then the value of a required number of units. The unitary method is also used to find the value of a single unit from a given multiple.
We need the equivalent length of 43 hectometres.
We multiply 43 with $0.1$ to get the length which will be equal to 43 hectometres.
Therefore, 43 hectometres are equal to $43\times 0.1=\text{4}\text{.3}$ kilometres.
Therefore, 43 hectometres are equal to $\text{4}\text{.3}$ kilometres.

Note: The hectometre and kilometre are units of measurement for length in both the US customary units and the metric systems of measurement. This unit is used in the normal or common measurement units. It can also be changed to other common measurement units using the relation in the metric system.
