Explanation:

Given : A student skipped a step when she tried to convert 11 Hours to seconds and she got the following incorrect result: 11 Hours (60 seconds/1 Minute)=660 seconds.

To find : What conversion ratio did she skip in this multiple-step equation?

Solution :

We have to convert 11 hours into seconds.

We know, 1 hour = 60 minutes

1 minute = 60 seconds

So,
`1\text{ hour}=60* 60\text{ minutes}`

`11\text{ hour}=60* 60* 11\text{ minutes}`

`11\text{ hour}=39600\text{ minutes}`

In the question, student converted 1 minute into 60 seconds but forgot to convert 1 hour into 60 minutes.

Therefore, The skipped conversion ratio is 60 minutes/1 hour.
