Question

(5,781 + 9,37) – 4,781;(3,23 + 8,596) + 8,77;8,123 - (2,123 + 1,8);​

Answer 1

Решение:

(5,781 + 9,37) – 4,781 = 5,781 - 4,781 + 9,37 = 1 + 9,37 = 10,37

(3,23 + 8,596) + 8,77 = 3,23 +8,77 + 8,596 = 12 + 8,596 = 20,596

8,123 - (2,123 + 1,8) = 8,123 - 2,123 - 1,8 = 6 - 1,8 = 4,2​

Answer 2

Ответ:

15,151-4,781=10,37

11,826+8,77=20,596

8,123-3,923=4,2

Answer 3

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

1. (5,781 + 9,37) - 4,781

   First, perform the addition inside the parentheses: 5.781 + 9.37 = 15.151

   Then, subtract 4.781 from the result: 15.151 - 4.781 = 10.37

   The final result is 10.37.

2. (3,23 + 8,596) + 8,77

   First, perform the addition inside the parentheses: 3.23 + 8.596 = 11.826

   Then, add 8.77 to the result: 11.826 + 8.77 = 20.596

   The final result is 20.596.

3. 8,123 - (2,123 + 1,8)

   First, perform the addition inside the parentheses: 2.123 + 1.8 = 3.923

   Then, subtract 3.923 from 8.123: 8.123 - 3.923 = 4.2

   The final result is 4.2.

Please note that the comma (,) is used here as a decimal separator, which might be different from the convention in some countries that use a period (.) as a decimal separator.
