don't remember how to do any of this
Have no idea of what #3 is 
When adding or subtracting fractions, you first must get a common denominator.
2/3  1/6 + 5/9 = 12/18  3/18 + 10/18 = 19/18 = 1 1/18
Please try the second one yourself.
I'm not sure about # 3. You'll probably get a response from another tutor if you post # 3 as a new question. 
do I change the mixed number with a common denminator or just the fradction part first?
4 1/3 = 13/3 =78/18
3 1/9 = 28/9 =56/18
2 1/2 = 5/2 =45/18
78/18 56/18 + 45/18 =67/18 =3 13/18
