Answer:

553/36 or 15 13/36

Explanation:

First change all to improper fractions with same denominator:

1 3/8 = 11/8

2 1/4 = 9/4

2 1/2 = 5/2

2 7/8 = 23/8

3 1/4 = 13/4

3 1/9 = 28/9

so the common denominator is 72

and then i did some math off the side ( i gtg soon so ill explain steps when i come back)

after you add all of them together you get 1106/72 which simplifies to 553/36 or 15 13/36
