Bill plays ball for 9 hours each week. His friend Mark spends as much time playing ball. Who plays more ball?
I think I have to divide. So I think Mark plays more ball by 10 4/5 hours. Is this correct? Thank you so very much for your help Ms. Sue.
You're welcome, Alice.
I think you left something out of your problem. How much time does Mark spend playing ball?
You later posted: "Oops! Mark spends 5/6 as much time playing ball."
(5/6) * 9 = 45/6 = 7 1/2 hours
Bill spends 1 1/2 hours more playing ball each week.
To determine who plays more ball, we need to compare the number of hours Bill plays to the number of hours Mark plays.
We are given that Bill plays for 9 hours each week. According to the information given, Mark spends as much time playing ball as Bill does.
Since Bill plays for 9 hours, Mark also plays for 9 hours each week.
Therefore, both Bill and Mark play the same amount of time, which is 9 hours. Neither of them plays more ball than the other.
So, your answer of Mark playing more ball by 10 4/5 hours is incorrect. Both Bill and Mark play for the same amount of time, which is 9 hours each week.
