To calculate this expression, we will first simplify each part separately:

Part 1: (-1,25) + 2
Calculating: -1,25 + 2 = 0,75

Part 2: 8 1/7
Calculating: 8 1/7 = 8/7

Part 3: 8/7 + 1/3
To add these fractions, we need to find a common denominator:
8/7 + 1/3 = 24/21 + 7/21 = 31/21

So the final result of the expression is:
0,75 + 31/21 = 0,75 + 1,476190476 = 2,226190476
