Question

(3-3.8:5 2/11)*3/7+(18-8 2/3):1 1/6 Решите пожалуйста по действиям

Answer 1

Можно спросить (я ответ в комментариях напишу, когда разбирусь)? 5 2/11, 8 2/3 это смешанные числа? Если да, то я не знаю как 3,8 делить на смешанное число. объясни пожалуйста все в комментариях

Answer 2

Calculation of Arithmetic Expression

To solve the given arithmetic expression, we'll follow the order of operations (PEMDAS/BODMAS) which stands for Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

The given expression is: (3-3.8:5+2/11) * 3/7 + (18-8+2/3) : 1 + 1/6

Let's break it down step by step:

1. 3-3.8:5+2/11 - First, we perform the division: 3.8 ÷ 5 = 0.76 - Then, we perform the subtraction: 3 - 0.76 = 2.24

2. 18-8+2/3 - First, we perform the division: 2 ÷ 3 = 0.6667 (rounded to 4 decimal places) - Then, we perform the subtraction: 18 - 8 = 10 - Finally, we perform the addition: 10 + 0.6667 = 10.6667

3. Now, we substitute the results back into the original expression: (2.24) * 3/7 + (10.6667) : 1 + 1/6

4. Next, we perform the multiplication and division from left to right: - (2.24) * 3 = 6.72 - 6.72 ÷ 7 = 0.96 - (10.6667) : 1 = 10.6667 - 10.6667 + 1/6 = 10.8333

Final Result

The final result of the given arithmetic expression is 10.8333.
