Jerry spent 5 1/3 hours cleaning the house. If he spent half that time cleaning the bathroom and 40 min cleaning his room, how much time did Jerry spend cleaning the rest of the house?
1 hour = 60 minutes
1/3 hour = 60/3= 20 minutes
5 hours= 300 minutes
5 1/3 hours= 320 minutes
therefore the answer is (320/2)-40
23
the answer is 40%
To find the amount of time Jerry spent cleaning the rest of the house, we need to subtract the time he spent cleaning the bathroom and his room from the total time spent cleaning.
First, let's convert the mixed number 5 1/3 into an improper fraction:
5 1/3 = (5 * 3 + 1) / 3 = 16/3
Now let's calculate the time Jerry spent cleaning the bathroom:
Since he spent half the total time cleaning the bathroom, we need to divide 16/3 by 2:
(16/3) / 2 = 16/6 = 8/3
Next, let's convert the 40 minutes he spent cleaning his room into hours:
40 minutes = 40/60 = 2/3 hours
Now, let's calculate the total time Jerry spent cleaning the bathroom and his room:
8/3 + 2/3 = 10/3
To find the time spent cleaning the rest of the house, we subtract the total time spent cleaning the bathroom and his room from the total time spent cleaning:
(16/3) - (10/3) = 6/3 = 2 hours
Therefore, Jerry spent 2 hours cleaning the rest of the house.
