Question

A new path that is 2.5 kilometers long is being built. So far, 1/5 of the path has been built. How long is the section that has been built?​

Answer 1

The section of the path that has been built = 0.5 km.

Explanation:

The total length of the path to be built = 2.5 km

Let us assume the section of the path that has been built = s km

Now, 1/5 the of the path is build.

⇒ s = 1/5 the of the total path

Now,
`(1)/(5) * (2.5) = 0.5`

⇒ s = 0.5 km

Hence, the section of the path that has been built = 0.5 km.
