227,36:(865,6-20,8*40,5) *8,38+1,12

To solve the expression \( 227.36 : (865.6 - 20.8 \times 40.5) \times 8.38 + 1.12 \), follow these steps: 1. Calculate the multiplication in the parentheses: \[ 20.8 \times 40.5 = 840.4 \] 2. Substitute back into the expression: \[ 227.36 : (865.6 - 840.4) \times 8.38 + 1.12 \] 3. Perform the subtraction: \[ 865.6 - 840.4 = 25.2 \] 4. Now the expression simplifies to: \[ 227.36 : 25.2 \times 8.38 + 1.12 \] 5. Perform the division: \[ 227.36 \div 25.2 \approx 9.004 \] 6. Then multiply by 8.38: \[ 9.004 \times 8.38 \approx 75.34732 \] 7. Finally, add 1.12: \[ 75.34732 + 1.12 \approx 76.46732 \] Thus, the final result is approximately \( 76.47 \) (rounded to two decimal places).
