A student skipped a step when she tried to convert 18 hours into seconds,
gladu [14]

Answer:

The conversion of minutes to seconds is skipped in multiple-step conversion.

Step-by-step explanation:

Given:

To convert 18 hours into seconds.

Now, to get the conversion ratio skip in this multiple-step conversion.

First we need to convert hours into minutes:

1 hour = 60 minutes.

So, 18 hours = 18\times 60 minutes

                     = 1080 minutes.

Then, we convert minutes into seconds:

1 minute = 60 seconds.

So, 1080 minutes = 1080\times 60 seconds

                             =  64800 seconds.

Thus, 18 hours =  64800 seconds.

<u>As given in question the conversion from hours to seconds is there but the conversion of minutes to second is not there it is skipped so the result is incorrect.</u>

Therefore, the conversion of minutes to seconds is skipped in multiple-step conversion.
