To solve the expression, we will first simplify the terms inside the parentheses:

6 - 3 5/8 = 6 - (3 + 5/8) = 6 - 3 - 5/8 = 3 7/8

Next, we will simplify the numbers in the brackets:

1,4 - 2,05 = 1.4 - 2.05 = -0.65

Now, we have:

5/9 (3 7/8) (-0.65) * 1.8

We will convert the mixed number to an improper fraction:

3 7/8 = 31/8

Now we have:

5/9 31/8 (-0.65) * 1.8

Multiplying the fractions:

(5 31) / (9 8) (-0.65) 1.8

155 / 72 (-0.65) 1.8

Now, multiply the numbers:

155 (-0.65) 1.8 / 72

-100.75 * 1.8 / 72

-181.35 / 72

= -2.52

Therefore, the final result of the expression is -2.52.
