B) 0,8-7-1,9: 3• 0,2

1) 1,9/3=19/10:3=19/30

2) 19/30*0.2=19/30*2/10=38/300=19/150

3) -7-19/150=(-1050-19)/150=-1069/150

4) 0.8-1069/150=8/10-1069/150=(120-1069)/150=-949/150= -6 49/150

Answer 2

It seems like you're providing a mathematical expression. Let's break down the expression step by step:

Expression: 0.8 - 7 - 1.9 : 3 • 0.2

1. First, perform the division: 1.9 : 3 = 0.633333...
2. Then, multiply the result by 0.2: 0.633333... * 0.2 = 0.126666...

Now, we can simplify the expression further:

Expression: 0.8 - 7 - 0.126666...

Subtracting the values:

0.8 - 7 = -6.2

Final result:

-6.2 - 0.126666... ≈ -6.32667...

So, the value of the expression is approximately -6.32667.
