hr. on her computer visiting the History Channel and the Discovery Channel websites. She spent 12
minutes at the history channel website. What fraction of an hour did she spend at the discovery channel website?

5/6 hour = 50 minutes

(50 - 12)/60 = ?

To find out what fraction of an hour Erika spent at the Discovery Channel website, we need to subtract the time she spent on the History Channel website from the total time.

Erika spent 5/6 hr. on her computer. We can represent this as a fraction: 5/6.

To convert this fraction into hours, we need to find a common denominator with the number of minutes in an hour, which is 60 minutes.

To convert 5/6 into minutes, we multiply the numerator (5) by 60 and divide by the denominator (6):

5/6 * 60 = (5 * 60) / 6 = 300/6 = 50 minutes.

So, Erika spent a total of 50 minutes on her computer.

Now, we know that she spent 12 minutes on the History Channel website. To find out how many minutes she spent on the Discovery Channel website, we subtract 12 from the total of 50 minutes:

50 minutes - 12 minutes = 38 minutes.

Therefore, Erika spent 38 minutes on the Discovery Channel website.

To express this as a fraction of an hour, we divide the number of minutes (38) by the number of minutes in an hour (60):

38/60 = 19/30.

Therefore, Erika spent 19/30 of an hour at the Discovery Channel website.
