8) 0,723 * 1000 : 2,41 + 12,29 * 0,01

Let's solve this expression step by step, following the order of operations (PEMDAS/BODMAS).

1. First, perform the multiplication: $$0.723 \times 1000 = 723$$
2. Next, perform the division: $$723 : 2.41 \approx 300$$
3. Now, perform the second multiplication: $$12.29 \times 0.01 = 0.1229$$
4. Finally, perform the addition: $$300 + 0.1229 = 300.1229$$

Therefore, the final answer is:

Answer: 300.1229
