To solve this expression, we need to use the properties of operations and rules for multiplying and dividing. Let's go step by step:
First, let's multiply the numbers in the numerator: (−3) × 27 × (−516) = 41,724.
Next, let's multiply the numbers in the denominator: 34 × 57 = 1,938.
Lastly, let's divide the numerator by the denominator: 41,724 ÷ 1,938 = 21.528.
Therefore, (−3) ÷ (34) × 27 × (−516) ÷ (57) equals approximately 21.528.
