54(388:12)-76

Let's simplify the expression step by step.

1. Start with the division inside the parentheses: \[ 388 \div 12 = 32.3333 \quad (\text{approximately}) \]

2. Then multiply this result by 54: \[ 54 \times 32.3333 \approx 1749.9992 \quad (\text{approximately } 1750) \]

3. Finally, subtract 76: \[ 1750 - 76 = 1674 \]

So, \(54(388:12)-76 \approx 1674\).
