Answer 3

To solve the expressions you provided, I'll go through each one step by step:

1. 919 This expression appears to be a simple number and not an arithmetic operation, so the result is 919 itself.

2. (6-2.43) : 4 Step 1: Subtract 2.43 from 6 6 - 2.43 = 3.57

Step 2: Divide the result by 4 3.57 ÷ 4 ≈ 0.8925

The result is approximately 0.8925.

3. (15.96) ÷ (9/25 + 2.04) Step 1: Add 9/25 and 2.04 9/25 + 2.04 = (9/25 + 2.04) ≈ 2.64

Step 2: Divide 15.96 by the result from Step 1 15.96 ÷ 2.64 ≈ 6.04

The result is approximately 6.04.

4. 1 ÷ (0.54 + 1.96) Step 1: Add 0.54 and 1.96 0.54 + 1.96 = 2.50

Step 2: Divide 1 by the result from Step 1 1 ÷ 2.50 = 0.4

The result is 0.4.

So, the solutions are:

1. 919
2. 0.8925
3. 6.04
4. 0.4
