Step 1: Convert mixed numbers to improper fractions

8 5/13 = (138 + 5)/13 = 109/13
5 9/11 = (115 + 9)/11 = 64/11
7 2/11 = (117 + 2)/11 = 79/11
5 3/8 = (85 + 3)/8 = 43/8
1 1/2 = (21 + 1)/2 = 3/2
1 1/2 = (21 + 1)/2 = 3/2
5 1/8 = (85 + 1)/8 = 41/8
5 2/9 = (95 + 2) = 47/9

Step 2: Perform multiplication and addition/subtraction

(109/13 64/11) + (79/11 43/8) - (3/2 5/8) - (47/9 9)

= (7016/143) + (3377/8) - (15/16) - (423/9)
= 7016/143 + 3377/8 - 15/16 - 423/9
= 49208/1144 + 45331/1144 - 1073/1144 - 5262/1144
= (49208 + 45331 - 1073 - 5262)/1144
= 88324/1144
= 77.29

So, the result is 77.29.
