To find out how many hours Erika spent at the Discovery Channel website, we need to subtract the time she spent at the History Channel website from the total time she spent on her computer.

First, let's start by finding out how much time Erika spent at the History Channel website. We know that she spent 1/5 hour at the History Channel website.

Next, to find out the total time she spent on her computer, we know that it is equal to 5/6 hour.

To find out how much time she spent at the Discovery Channel website, we can subtract the time spent at the History Channel website from the total time spent on her computer.

1. Subtract the time spent at the History Channel website:
Total time spent at the Discovery Channel website = Total time spent on her computer - Time spent at the History Channel website

Total time spent at the Discovery Channel website = 5/6 hour - 1/5 hour

To subtract fractions with different denominators, we need to find a common denominator. In this case, the common denominator is 30 (5 multiplied by 6 and 6 multiplied by 5).

2. Convert the fractions to have the common denominator:
Total time spent at the Discovery Channel website = (5/6) * (5/5) - (1/5) * (6/6)

After simplifying the fractions, we have:

Total time spent at the Discovery Channel website = 25/30 - 6/30

3. Subtract the fractions:
Total time spent at the Discovery Channel website = (25 - 6) / 30

Total time spent at the Discovery Channel website = 19/30 hour

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