(8 7/12-2 17/36) *2,7 - 4 1/3 : 0,65

Let's compute step by step, using the European decimal comma.

1. Convert mixed numbers:

• 8 7/12 = 103/12
• 2 17/36 = 89/36
• Difference: 103/12 − 89/36 = 309/36 − 89/36 = 220/36 = 55/9

2. Multiply by 2,7 (which is 27/10):

• (55/9) × (27/10) = (55×27)/(9×10) = (55×3)/10 = 165/10 = 33/2 = 16,5

3. Compute the last division: 4 1/3 ÷ 0,65

• 4 1/3 = 13/3
• 0,65 = 65/100 = 13/20
• (13/3) ÷ (13/20) = (13/3) × (20/13) = 20/3 ≈ 6,666...

4. Subtract:

• 33/2 − 20/3 = (99 − 40)/6 = 59/6

Final result:

• Exact: 59/6
• Mixed: 9 5/6
• Decimal: 9,8333... (repeating 3), i.e., approximately 9.8333

If you’d like, I can present it in a single decimal or as a check using a calculator.
