To solve the expression \( 355.1 : 0.67 + 0.83 \cdot 15 \), we will follow the order of operations (PEMDAS/BODMAS).
First, perform the division: \[ 355.1 \div 0.67 \approx 530.1492537 \]
Next, perform the multiplication: \[ 0.83 \cdot 15 = 12.45 \]
Finally, add the two results together: \[ 530.1492537 + 12.45 \approx 542.5992537 \]
Thus, the result is approximately: \[ \approx 542.60 \] (rounded to two decimal places).
