Answer:
5 4/6 or 5 and 2/3 hours
Explanation:
I only see question 8 not any other questions so I can only answer question 8 If you send me what the other question is I will answer it for you.
First we will find how many hours in June and July Mary spent at the pet shelter.
2 1/2 + 1 2/3 = 2 3/6 + 1 4/6 = 4 1/6
So Mary spent 4 and 1/6 hours at the pet shelter in June and July.
Now we know that she spent as many hours at the pet shelter in August as June so we take June's time and add it to 4 and 1/6.
4 1/6 + 2 3/6 = 5 4/6 or 5 and 2/3 hours
