Ответ: 8,2

Answer 2

Ответ:

4*0.85-1/7/5/14-1,56/(-0,3)=41/5=8,2

Пошаговое объяснение:

1)4*0,85=3,4

2)(1/7)/(5/14)=2/5

3)1,56/(-0,3)=(39/25)/(-3/10)

   а)1,56=39/25

   б)-0,3=-3/10

4)3,4=17,5

5)(39/25)/(3/10)=26/5

6)(17/5)-(2/5)+(26/5)=41/5

Answer 3

Let's break down the expression step by step:

1. 4 * 0.85 = 3.4

2. 1 / 7 = 0.142857...

3. 5 / 14 = 0.357142...

4. Now, we divide 0.142857... by 0.357142...: (1 / 7) / (5 / 14) = (1 / 7) * (14 / 5) = 2 / 35 ≈ 0.057142...

5. 3.4 - 0.057142... = 3.342857...

6. Now, we have to handle the fraction 56 / (-0.3). Since the denominator is negative, we need to be careful: 56 / (-0.3) = -186.666...

7. Finally, we subtract -186.666... from 3.342857...: 3.342857... - (-186.666...) ≈ 189.008...

So, the result of the expression is approximately 189.008.
