Answer 2

To solve the given expression, let's break it down step by step:

Step 1: Calculate the expression inside the innermost parentheses. 1,11/20 - 0,945 : 0,9

Step 2: Perform the division in the innermost parentheses. 0,945 / 0,9 = 1.05

Step 3: Calculate the result inside the outer parentheses. 9 * (1.11/20 - 1.05) = 9 * (0.0555) = 0.4995

Step 4: Evaluate the division operations from left to right. 10.5 * 0.24 - 15.15 : 7.5 = 2.52 - 2.02 = 0.5

Step 5: Calculate the final result. 0.5 / (1.3/40 - 4.3/8 : 7)

Step 6: Perform the division inside the parentheses. 4.3 / 8 = 0.5375 0.5375 : 7 = 0.07678571429 (approximately)

Step 7: Calculate the final result. 0.5 / (1.3/40 - 0.07678571429)

Step 8: Perform the division inside the parentheses. 1.3 / 40 = 0.0325

Step 9: Calculate the final result. 0.5 / (0.0325 - 0.07678571429)

Step 10: Perform the subtraction. 0.0325 - 0.07678571429 = -0.04428571429

Step 11: Calculate the final result. 0.5 / (-0.04428571429)

Step 12: Perform the division. Result ≈ -11.2878604613

Therefore, the final result of the expression is approximately -11.2879.
