Final answer:
Brynn played for a total of 7 hours and 11 minutes.
Step-by-step explanation:
To find the total number of hours Brynn played, we need to add the time she played on Saturday and Sunday.
Brynn played for 3 2/3 hours on Saturday and 4 ¼ hours on Sunday. To add these fractions, we need to convert them to a common denominator, which is 12.
Converting 2/3 to twelfths, we get 8/12, and converting 1/4 to twelfths, we get 3/12. So, 3 2/3 hours + 4 1/4 hours equals 3 8/12 hours + 4 3/12 hours, which is equal to 7 11/12 hours.
