Anew 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?

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

Step-by-step 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,

⇒ s = 0.5 km

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