Answer 2

Sure, I can help you solve these mathematical expressions! Here are the solutions:

1. (48,72/1,2+1,696/0,32)*1,2-3,4

First, we need to simplify the expression inside the parentheses:

48.72 / 1.2 = 40.6 1.696 / 0.32 = 5.3

So now we have:

(40.6 + 5.3) * 1.2 - 3.4

Next, we can simplify the expression inside the parentheses:

40.6 + 5.3 = 45.9

So now we have:

45.9 * 1.2 - 3.4

Multiplying 45.9 by 1.2, we get:

55.08 - 3.4

Subtracting 3.4 from 55.08, we get:

51.68

Therefore, the solution is 51.68.

2. 24-(1,0098/0,054+2,47)

First, we need to simplify the expression inside the parentheses:

1.0098 / 0.054 = 18.7

So now we have:

24 - (18.7 + 2.47)

Next, we can simplify the expression inside the parentheses:

18.7 + 2.47 = 21.17

So now we have:

24 - 21.17

Subtracting 21.17 from 24, we get:

2.83

Therefore, the solution is 2.83.

3. (1,43+2,145)/0,65-(2*1,45-2,7)*3,68

First, we need to simplify the expression inside the parentheses:

2 * 1.45 = 2.9

2.9 - 2.7 = 0.2

So now we have:

(1.43 + 2.145) / 0.65 - 0.2 * 3.68

Adding 1.43 and 2.145, we get:

3.575

So now we have:

3.575 / 0.65 - 0.2 * 3.68

Dividing 3.575 by 0.65, we get:

5.5 - 0.2 * 3.68

Multiplying 0.2 by 3.68, we get:

0.736

So now we have:

5.5 - 0.736

Subtracting 0.736 from 5.5, we get:

4.764

Therefore, the solution is 4.764.
