I will do one or two for you, then you can understand and do the rest. In all of them, you need the LCD (least common denominator) to combine them.
3/6 + 3/4 = 6/12 + 9/12 = 15/12 = 1 3/12 = 1 1/4
7/9 - 1/3 = 7/9 - 3/9 = 4/9
Good luck!

if i do them then you'l never learn...
I'l do one as an example, this is how I learned how to do them...
3/6 + 3/4 = you find the common demonator of the two numbers underneath which are 6 and 4. the answer is 12 because 6 and 4 both devide into 12.
so then you divide 6 into 12 which is 2 and then you multiply that by the top so the answer is 6. then you divide 4 into 12 and you get 3. then mulitiply it by 3 and you get 9. So then you add 6 and 9 and you get 15. you put this over 12. so its 15/12, which is 1 3/12 or 1 1/4.
Do you get it??

The problem with your question, is that you are just looking for answers. You still won't understand how to do these for yourself. If you want help understanding, I, and many others on this site, would be glad to help you. If you are looking for quick easy answers, that's just cheating.
