Answer 1

Ответ:

1)-0,6:(-2) - 2*(-3):(-2,4) + (-2,3)=

0,3- 2,5-2,3=-4,5

2) 6,4 -2*(-16):(-0,1): 400=

6,4-320/400=6,4-0,8=5,6

3) -7,7:11 + (-5,8):(26 :(-13))=

-0,7+2,9=2,2

4) 56 : (-0,08) =-700

Answer 2

Let's solve each of these expressions step by step:

1. -0.6 / (-2) - 2 * (-3) / (-2.4) + (-2.3)

First, we'll simplify the division and multiplication:

1. 0.3 + 3 * 1.25 + (-2.3)

Now, calculate the multiplication:

1. 0.3 + 3.75 + (-2.3)

Now, add and subtract:

1. (0.3 + 3.75) + (-2.3)
2. 4.05 - 2.3

Finally, subtract:

1. 1.75

So, the result of the first expression is 1.75.

2. 6.4 - 2 * (-16) / (-0.1) / 400

First, we'll simplify the multiplication and division: 2) 6.4 + 32 / (-0.1) / 400

Now, simplify further: 2) 6.4 + (-320) / 400

Now, calculate the division: 2) 6.4 - 0.8

Finally, subtract: 2) 5.6

So, the result of the second expression is 5.6.

3. -7.7 / 11 + (-5.8) / (26 / (-13))

First, calculate the division inside the second part of the expression: 3) -7.7 / 11 + (-5.8) / (-2)

Now, calculate the divisions: 3) -0.7 - (-2.9)

Now, subtract: 3) -0.7 + 2.9

3. 2.2

So, the result of the third expression is 2.2.

4. 56 / (-0.08) / (-) / 3

It seems there's a missing value or operator in the fourth expression, indicated by the "(-)" symbol. Please provide the missing value or operator for me to continue solving this expression.
