Question

19, 5 :( 3, 5 - 1 11 / 20 ) - 0, 555 : 0, 15

Answer 1

19,5:(3,5-1,55)-0,555:0,15=19,5:1,95-3,7=10-3,7=6,3

1 11/20=1,55

Answer 2

Let's break down the expression step by step:

1. Start with the first part: 19, 5

2. Next, calculate the value inside the parentheses: (3, 5 - 1 11 / 20)

   a. 11 / 20 = 0.55 b. 5 - 1 = 4 c. 3, 4 (using the comma as a decimal separator) = 3.4

3. So, the expression becomes: 19, 5 - 3.4

4. Now, calculate the second part: 0, 555 : 0, 15

   a. 555 / 15 = 37

5. So, the expression becomes: 19, 5 - 3.4 - 37

6. Finally, calculate the result: 19, 5 - 3.4 - 37 = 16,1 - 37 (again, using the comma as a decimal separator)

7. Subtract 37 from 16,1: 16,1 - 37 = -20.9

So, the final result of the expression is -20.9.
