The correct answer is 16.
To solve the expression (-2) × (15) ÷ (23) × (-56) ÷ (34), follow the order of operations which is parentheses, multiplication and division from left to right.
First, perform the multiplication (-2) × (15) = -30.
Then, perform the division -30 ÷ (23) = -30/23 ≈ -1.304.
Note: Keep the fraction in decimal form for the next step.
Next, perform the multiplication -1.304 × (-56) = 72.864.
Finally, perform the division 72.864 ÷ (34) = 72.864/34 ≈ 2.143.
Thus, the answer is approximately 2.143.
To solve the expression (-2) × (15) ÷ (23) × (-56) ÷ (34), we need to follow the properties of operations and rules for multiplying and dividing.
Step 1: Perform the multiplications
-2 × 15 = -30
-30 × -56 = 1680
Step 2: Perform the divisions
1680 ÷ 23 ≈ 73.043
73.043 ÷ 34 ≈ 2.151
So, the value of the expression is approximately 2.151.
Therefore, the correct answer is "Start Fraction 2 over 3 End Fraction".

Apologies for the confusion. Upon reviewing the previous response, I made an error in the final step of the calculations.
Step 1: Perform the multiplications
-2 × 15 = -30
-30 × -56 = 1680
Step 2: Perform the divisions
1680 ÷ 23 ≈ 73.043
73.043 ÷ 34 ≈ 2.15
So, the value of the expression is approximately 2.15.
Therefore, the correct answer is "2.15".

Apologies for the confusion. Let's go through the steps to solve the expression again.
Step 1: Perform the multiplication (-2) × (15) = -30.
Step 2: Perform the division -30 ÷ (23) = -30/23.
Step 3: Perform the next multiplication (-30/23) × (-56) = 1680/23.
Step 4: Perform the final division (1680/23) ÷ (34) = 40/69.
Therefore, the correct answer is "Start Fraction 40 over 69 End Fraction".

To solve the expression (9) ÷ (54) × (79) × (-5) ÷ (72), follow the order of operations which is parentheses, multiplication and division from left to right.
Step 1: Perform the division (9) ÷ (54) = 1/6.
Note: Keep the fraction in fractional form for the next steps.
Step 2: Perform the multiplication (1/6) × (79) = 79/6.
Step 3: Perform the multiplication (79/6) × (-5) = -395/6.
Step 4: Perform the division (-395/6) ÷ (72) = -(395/6) ÷ (72) = -(395/6) × (1/72) = -395/432.
Therefore, the answer is -395/432.
So, the correct answer is "negative Start Fraction 395 over 432 End Fraction".
