Amy watched television for 2 3/4 hours. Charles watched television for 1/3 of the time Amy did. How long, in minutes did Charles watch television.
2 3/4 - 1/3
right?
No.
You need to multiply 1/3 times 2 3/4
Since your answer must be in minutes, you should change the 2 3/4 hours to minutes.
Or you can change your answer to minutes.
i got 11/12 so i guest your reduce it in order to find the minutes
11/12 can't be simplified. But you need to remember that 1 hour = 60 minutes.
Let's change 2 3/4 to minutes.
2 3/4 * 60 = 165 minutes
1/3 * 165 = 55 minutes
11/12 * 60 = 55 minutes
I just realize it
anyways thank you soo much for making this clear for me to understand this problem
because at first I was struggling
again thank you! :)
You're very welcome, Laruen.
To find out how long Charles watched television, we need to subtract 1/3 of the time Amy watched from the total time Amy watched.
First, let's convert the mixed number 2 3/4 to an improper fraction.
2 3/4 = (2 * 4 + 3) / 4 = 11/4
Now we can subtract 1/3 from 11/4:
11/4 - 1/3
To subtract fractions, we need a common denominator. In this case, the least common multiple (LCM) of 4 and 3 is 12.
So, let's convert both fractions to have a denominator of 12:
11/4 = (11 * 3) / (4 * 3) = 33/12
1/3 = (1 * 4) / (3 * 4) = 4/12
Now we can subtract the fractions:
33/12 - 4/12 = 29/12
To convert this back to a mixed number, we divide the numerator (29) by the denominator (12):
29 รท 12 = 2 remainder 5
Therefore, the answer is 2 5/12.
Since we know that 1 hour has 60 minutes, we need to convert the mixed number to minutes:
2 hours = 2 * 60 = 120 minutes
5/12 * 60 = 25 minutes
So, Charles watched television for a total of 120 + 25 = 145 minutes.
