Question

(0,8 : 2ц 2/3 - 0,12) : (1,26 * 4/7 +0.08)

Answer 1

Ответ:

Пошаговое объяснение:

1) 0,8:2 2/3=8/10:8/3=8/10*3/8=3/10

2)3/10-0,12=0,3-0,12=0,18

3)1,26*4/7=1 26/100*4/7=126/100*4/7=18/25

4)18/25+0,08=0,72+0,08=0,8

5)0,18:0,8=0,225

Answer 2

To solve the expression, let's first clarify the symbols used:

• "," is used as a decimal separator.
• ":" denotes division.

Now, let's proceed with the calculation step by step:

Step 1: Calculate the expression within the first parentheses. 2ц 2/3 - 0.12

To calculate ц (pronounced "pi"), we will use the value 3.14159 (approximate value of pi).

2ц 2/3 = 2 * 3.14159 + 2/3 ≈ 6.28318 + 0.66667 ≈ 6.94985

Now, the expression becomes: 6.94985 - 0.12 ≈ 6.82985

Step 2: Calculate the expression within the second parentheses. 1.26 * 4/7 + 0.08

1.26 * 4/7 ≈ 0.72

Now, the expression becomes: 0.72 + 0.08 ≈ 0.80

Step 3: Divide the results from Step 1 and Step 2.

(6.82985 : 0.80) ≈ 8.53731

The final result of the expression is approximately 8.53731.
