Answer 2

An audio cable is 15.9 dm long. The length of the audio cable in metre is 159m

Solution:

Given that audio cable is 15.9 dm long. We have to convert 15.9 decimetre to meter.

To convert decimetre(m) to metre(cm) we use the given formula

We know,

1m =10 dm

Therefore to convert any number in decimetre (dm) to metre (m) we multiply the given number by 10.

Here we have to convert 15.9 dm to m. Therefore multiplying 15.9 with 10 we get,

`15.9 * 10 = 159 m`

Thus the length of the cable in metre is 159 m.
