Answer 2

To solve the expression, let's break it down step by step:

(0,3 - 3/20) * 2 - 6/7 - 2/5 : 1,4

Step 1: Inside the parentheses, we have subtraction and division.

0.3 - 3/20 = 0.3 - 0.15 = 0.15

So the expression becomes:

0.15 * 2 - 6/7 - 2/5 : 1,4

Step 2: Multiplication:

0.15 * 2 = 0.3

So the expression becomes:

0.3 - 6/7 - 2/5 : 1,4

Step 3: Subtraction:

0.3 - 6/7 ≈ 0.3 - 0.857 ≈ -0.557

So the expression becomes:

-0.557 - 2/5 : 1,4

Step 4: Division:

-2/5 ÷ 1 = -2/5

So the expression becomes:

-0.557 - 2/5 : 4

Step 5: Division:

-2/5 ÷ 4 = -1/10

Finally, the expression simplifies to:

-0.557 - 1/10 ≈ -0.657

So, the result is approximately -0.657.
