To solve this expression, we first need to simplify the terms:

(5,07;1/20-23,4:13/50) = 5.07 - (20 - 23.4 ÷ 13/50)
= 5.07 - (20 - 23.4 × 50/13)
= 5.07 - (20 - 90.8)
= 5.07 - (-70.8)
= 75.87

0.074 × 1/2 = 0.037

Now, we substitute these simplified terms back into the original expression and calculate:

(75.87) × 1/4 + 0.037 = 18.9675 + 0.037
= 19.0045

Therefore, the result of the expression is 19.0045.
