To solve the expression \((-3) \div (34) \times (27) \times (-516) \div (57)\), we can use the properties of operations. Here's a step-by-step breakdown:

  1. Rewrite the Expression: \[ (-3) \div 34 \times 27 \times (-516) \div 57 \]

  2. Group the Multiplications and Divisions: \[ = \left((-3) \div 34 \times (-516)\right) \div 57 \times 27 \]

  3. Handle Division First: Calculate \((-3) \div 34\): \[ = -\frac{3}{34} \] Now we have: \[ -\frac{3}{34} \times 27 \times (-516) \div 57 \]

  4. Calculate \(-3/34 \times 27\): \[ -\frac{3 \times 27}{34} = -\frac{81}{34} \]

  5. Next, Multiply by -516: \[ -\frac{81}{34} \times (-516) = \frac{81 \times 516}{34} \]

  6. Calculate \(81 \times 516\): \[ = 41796 \] Now, we need to divide by \(34\): \[ \frac{41796}{34} \]

  7. Divide: \[ 41796 \div 34 = 1235.176 \]

  8. Divide by 57: \[ \frac{1235.176}{57} \] \[ = 21.68 \]

Therefore, the final result of the expression \((-3) \div (34) \times (27) \times (-516) \div (57)\) is approximately 21.68.
