Pls help I don’t understand

1. 7 1/4

2. 3 1/4

3. 2 2/3

4. 2 1/2

Step-by-step explanation:

1. You subtract 8-3/4=7 1/4

2. You have to add 2 3/4 hour + 1/2 an hour = 3 1/4 hours

3. You take 3 2/6 - 2/3= to make it easier you want to change the fractions so there the same denominator 2/6->1/3 now it will be much easier to subtract 3 1/3-2/3= 2 2/3

4. Finally you do 8-5 1/2 =2 1/2

I hope this helps if not you can comment and I'll try and further explain
