Question

(6/35-4/7) - (-1,8-4,3)-5,7(3,9-5.8)- (-1/45-7/9)+1,1 помогите пожалуйста

Answer 1

(6/35-4/7) - (-1,8-4,3)-5,7=0
1)6\35-4\7=6\35-20\35=-14\35=-2\5=-0.4
2)-1.8-4.3=-6.1
3)-0.4-(-6.1)=-0.4+6.1=5.7
4)5.7-5.7=0


(3,9-5.8)- (-1/45-7/9)+1,1=0
1)3.9-5.8=-1.9
2)-1\45-7\9=-1\45-35\45=-36\45=-0.8
3)-1.9-(-0.8)=-1.9+0.8=-1.1
4)-1.1+1.1=0

Answer 2

И в первом и во втором примере ответ 0

Answer 3

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

Step 1: Simplify the fractions

The expression contains fractions, so let's simplify them first.

6/35 can be simplified to 6/35 = 3/17 4/7 remains as it is. -1/45 can be simplified to -1/45.

Step 2: Perform the arithmetic operations

Now, let's perform the arithmetic operations in the given expression.

6/35 - 4/7 = 3/17 - 4/7 -1.8 - 4.3 = -6.1 3.9 - 5.8 = -1.9 -1/45 - 7/9 = -1/45 - 35/45

Step 3: Simplify the expressions further

Let's simplify the remaining expressions.

3/17 - 4/7 cannot be simplified further. -1/45 - 35/45 = -36/45 = -4/5

Step 4: Perform the remaining operations

Now, let's perform the remaining operations.

3/17 - 4/7 - 1.8 - 4.3 - 5.7(-1.9) - (-4/5) + 1.1

Step 5: Calculate the final result

Let's calculate the final result.

3/17 - 4/7 - 1.8 - 4.3 - 5.7(-1.9) - (-4/5) + 1.1 = -0.176 - 0.571 - 1.8 - 4.3 - 5.7(-1.9) + 4/5 + 1.1

Now, let's calculate the value of -5.7(-1.9):

-5.7(-1.9) = -5.7 * -1.9 = 10.83

Substituting this value back into the expression:

-0.176 - 0.571 - 1.8 - 4.3 - 10.83 + 4/5 + 1.1

Now, let's calculate the final result:

-0.176 - 0.571 - 1.8 - 4.3 - 10.83 + 4/5 + 1.1 = -19.956 + 0.8 + 1.1

-19.956 + 0.8 + 1.1 = -18.056

Therefore, the value of the given expression is -18.056.

I hope this helps! Let me know if you have any further questions.
