Answer 2

Let's solve each of the expressions step by step:

1. 53,104 + 4,6 * (12 - 13,23 / 1,26) - 8,04

Step 1: Perform the division inside the parentheses 13,23 / 1,26 = 10.476190476190476...

Step 2: Perform the subtraction inside the parentheses 12 - 10.476190476190476... = 1.5238095238095238...

Step 3: Perform the multiplication 4.6 * 1.5238095238095238... = 7.012987012987013...

Step 4: Perform the addition and subtraction 53.104 + 7.012987012987013... - 8.04 ≈ 52.077987012987...

The approximate result is 52.078.

2. 3.6 / (68.1 / 1.5 - 11.42 + 2.02) * 100

Step 1: Perform the division inside the parentheses 68.1 / 1.5 = 45.4

Step 2: Perform the addition and subtraction inside the parentheses 45.4 - 11.42 + 2.02 = 36

Step 3: Perform the division 3.6 / 36 = 0.1

Step 4: Multiply by 100 0.1 * 100 = 10

The result is 10.

3. (0.12 * 10 - 0.216 / 0.2) / 0.03 + 2.7

Step 1: Perform the multiplication 0.12 * 10 = 1.2

Step 2: Perform the division 0.216 / 0.2 = 1.08

Step 3: Perform the addition and subtraction 1.2 - 1.08 = 0.12

Step 4: Perform the division 0.12 / 0.03 = 4

Step 5: Perform the addition 4 + 2.7 = 6.7

The result is 6.7.

4. (0.4 * 1.25 - 0.3) / 0.04 - 3.724 + 0.23

Step 1: Perform the multiplication 0.4 * 1.25 = 0.5

Step 2: Perform the subtraction 0.5 - 0.3 = 0.2

Step 3: Perform the division 0.2 / 0.04 = 5

Step 4: Perform the addition and subtraction 5 - 3.724 + 0.23 ≈ 1.506

The approximate result is 1.506.

So, the results are:

1. 52.078
2. 10
3. 6.7
4. 1.506
