First, let's simplify the expression inside the parentheses:
4,2 - 13/40 = 4,2 - 0.325 = 3.675
Now, let's simplify the expression inside the square brackets before the multiplication:
0,4:2,1/2 = 0.4 / (2 + 0.5)= 0.4 / 2.5 = 0.16
Next, let's multiply the two simplified expressions:
(1,35 + 0.16) • 3.675 = 1.51 • 3.675 = 5.55
Therefore, the final answer to the expression is 5.55.
