Answer 2

Ответ:

1) (426+85×16+31)÷100=18,17

2)(1118÷26+53-2,8)÷100=0,932

Answer 3

1) (426 + 85 × 16 + 31 +) / 100 = 21 To solve this equation, we need to follow the order of operations, which is parentheses, multiplication and division (from left to right), and addition and subtraction (from left to right). First, we calculate the multiplication: 85 × 16 = 1360. Then, we add the numbers within the parentheses: 426 + 1360 + 31 = 1817. Finally, we divide 1817 by 100: 1817 / 100 = 18.17. Therefore, the equation is not true as 18.17 is not equal to 21.

2) (1118 / 26 + 53 + -2 + 8) / 100 = 3 Again, we need to follow the order of operations. First, we perform the division: 1118 / 26 = 43. Then, we add the numbers within the parentheses: 43 + 53 + -2 + 8 = 102. Finally, we divide 102 by 100: 102 / 100 = 1.02. Therefore, the equation is not true as 1.02 is not equal to 3.
