5/6 * 60 = 50 minutes
50 - 12 = 38
38/60 = 19/30
I have no clue how to start this can anyone help me?
50 - 12 = 38
38/60 = 19/30
So, let’s do some math! There are 60 minutes in an hour, right? So, 12 minutes is equivalent to 12/60 = 1/5 of an hour.
Since Erika spent 5/6 of an hour on her computer in total and 1/5 of an hour at the history channel website, we can subtract these two fractions to find the remaining fraction of an hour she spent at the discovery channel website.
So, to find out, let's grab our clown calculator!
Calculating... *drumroll*
(5/6) - (1/5) = (20/30) - (6/30) = 14/30 = 7/15
Voila! Erika spent 7/15 of an hour at the discovery channel website.
Given that Erika spent 5/6 hr. on her computer, we know that this is the total time she spent on both the history and discovery channel websites.
To find the fraction of an hour that Erika spent at the discovery channel website, we need to subtract the time she spent at the history channel website from the total time.
So, let's calculate:
Total time spent on both websites = 5/6 hr.
Time spent at the history channel website = 12 minutes.
Now, we need to convert the time spent at the history channel website to hours. Since there are 60 minutes in an hour, we divide 12 minutes by 60:
12 minutes ÷ 60 minutes/hour = 1/5 hr.
Next, we subtract the time spent at the history channel website from the total time:
5/6 hr. - 1/5 hr. = ?
To subtract these fractions, we need to find a common denominator. In this case, the denominators are 6 and 5, so the common denominator is 30.
5/6 hr. = 25/30 hr. (multiplied numerator and denominator by 5)
1/5 hr. = 6/30 hr. (multiplied numerator and denominator by 6)
Now, subtract the fractions:
25/30 hr. - 6/30 hr. = (25 - 6) / 30 = 19/30 hr.
Therefore, Erika spent 19/30 hr. at the discovery channel website.
We are given that Erika spent 5/6 hour on her computer visiting the history and discovery channel websites. We also know that she spent 12 minutes at the history channel website.
To find out what fraction of an hour Erika spent at the discovery channel website, we need to subtract the time spent at the history channel from the total time spent on the computer.
To do this, we first convert the 12 minutes into an hour. There are 60 minutes in an hour, so we have:
12 minutes ÷ 60 minutes = 1/5 hour
Now, we subtract this fraction from the total time:
5/6 hour - 1/5 hour = ?
To subtract fractions, we need a common denominator. In this case, the common denominator is 30, which is the least common multiple of 6 and 5.
Now, let's convert both fractions to have a denominator of 30:
(5/6) x (5/5) = 25/30
(1/5) x (6/6) = 6/30
Now we can subtract the fractions:
25/30 - 6/30 = 19/30
Therefore, Erika spent 19/30 hour at the discovery channel website.
