Question

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%
