Объяснение:

$-1,2-(-4,3-7,1):3=-1,2-(-(4,3+7,1)):3=-1,2+11,4:3=$

$=(9+2,4):3-1,2=9:3+2,4:3-1,2=3+0,8-1,2=3-0,4=2,6;$

Answer 2

To solve this expression, we need to follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right).

The expression you provided is:

-1,2 - (-4,3 - 7,1) ÷ 3

1. Start by evaluating the innermost parentheses:

   -4,3 - 7,1 = -4,3 + (-7,1) = -4,3 - 7,1 = -11,4

2. Now, you can rewrite the expression:

   -1,2 - (-11,4) ÷ 3

3. Continue with the subtraction inside the parentheses:

   -1,2 - (-11,4) = -1,2 + 11,4 = 10,2

4. Now, the expression becomes:

   10,2 ÷ 3

5. Finally, perform the division:

   10,2 ÷ 3 ≈ 3,4

So, the result of the expression is approximately 3.4.
