Answer 2

To calculate the given expression, follow these steps:

Step 1: Simplify each fraction.

7.1/2 = 7.1 ÷ 2 = 3.55

3.9/11 = 3.9 ÷ 11 ≈ 0.354545

11/49 = 11 ÷ 49 ≈ 0.22449

21/22 ≈ 0.954545

3.3/4 = 3.3 ÷ 4 = 0.825

Step 2: Perform the operations inside the parentheses.

11/49 * 21/22 = 0.22449 * 0.954545 ≈ 0.214286

3.3/4 = 0.825

Adding them together: 0.214286 + 0.825 ≈ 1.039286

Step 3: Calculate the final result.

3.55 - 0.354545 - 1.039286 ≈ 2.155169

Therefore, the result of the expression 7.1/2 : 3.9/11 - (11/49 * 21/22 + 3.3/4) is approximately 2.155169.
