54(388:12)-76

To solve the expression \( 54(388:12) - 76 \), we first need to simplify \( 388:12 \).

1. Calculate \( 388 \div 12 \): \[ 388 \div 12 = 32.3333 \quad (\text{or } 32 \frac{1}{3}, \text{ or } \frac{388}{12}) \]

2. Now, we will use the decimal form (or a fraction if preferred) in the next step, so: \[ 54(32.3333) - 76 \]

3. Next, calculate \( 54 \times 32.3333 \): \[ 54 \times 32.3333 \approx 1749.9992 \quad (\text{which is approximately } 1750) \]

4. Now, subtract 76 from the result: \[ 1750 - 76 = 1674 \]

Thus, the final result of the expression \( 54(388:12) - 76 \) is approximately 1674.
