Answer 2

The audio cable is 1.59 m long.

Solution:

Given, the length of audio cable is 15.9 dm

To find, the length of the cable in meters.

One decimeter is
`10^(-1)` meters, i.e. 1 dm =
`10^(-1) m =  (1)/(10) m`

So, in order to convert decimeter to meter, we have to multiply the given decimeter value by
`10^(-1) m` or
`(1)/(10) m`

Length of the audio cable is
`15.9*(1)/(10) = 1.59 meters`

Or
`15.9*10^(-1)=1.59 meters`

`\therefore` the audio cable is 1.59 m long.
