Answer 1

I know the answer my math teacher said it would be 3 1/2 hours

Answer 2

2 1/2= 2 2/4
3/4 + 1/4 =4/4 or 1
convert 2 2/4 into an improper fraction: 10/4
10/4+4/4=14/4
14/4 simplifies into 3 2/4 hours
3 and 2/4 simplifies into 3 and 1/2
Mariana spent 3 and 1/2 hours doing all the activities
