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
