Answer 3

Let's break down the expression step by step:

-27/4:1 5/6-1,6*(-0,3)

First, let's simplify the division:

-27/4 = -6.75

So now we have:

-6.75:1 5/6-1,6*(-0,3)

Next, let's convert the mixed number to an improper fraction:

1 5/6 = (6*1 + 5)/6 = 11/6

So now we have:

-6.75:11/6-1,6*(-0,3)

Next, let's simplify the multiplication:

-1.6*(-0.3) = 0.48

So now we have:

-6.75:11/6-0.48

To simplify the division, we can multiply by the reciprocal of 11/6:

-6.75 * 6/11 = -3.681818...

So now we have:

-3.681818... - 0.48

Next, let's simplify the subtraction:

-3.681818... - 0.48 = -4.161818...

So now we have:

-4.161818...

Now let's move on to the second part of the expression:

-9,5:(5 7/10-4 12/35)

First, let's convert the mixed numbers to improper fractions:

5 7/10 = (10*5 + 7)/10 = 57/10

4 12/35 = (35*4 + 12)/35 = 152/35

So now we have:

-9.5:(57/10-152/35)

To simplify the subtraction in the denominator, we need a common denominator:

57/10 = (3*19)/2

152/35 = (5*30 + 2)/7 = 152/35

So now we have:

-9.5:((3*19)/2-152/35)

Next, let's simplify the expression in the parentheses:

(319)/2-152/35 = 57/2 - 152/35 = (3557 - 2*152)/70 = 1099/70

So now we have:

-9.5:(1099/70)

To divide by a fraction, we can multiply by its reciprocal:

-9.5 * 70/1099 = -0.606005...

So the final simplified expression is:

-4.161818... - 0.606005... = -4.767823... (rounded to 6 decimal places)
