15.4/2 - 2*(6.2 - 15.6)
- -11.1.
- 11.1.
- 26.5.
Explanation
Apply order of operations: division and multiplication before subtraction. 15.4/2=7.7, and 6.2-15.6=-9.4 so 2*(-9.4)=-18.8. Subtracting a negative gives 7.7-(-18.8)=7.7+18.8=26.5.

26.5 is correct!
15,4/2=7,7
(6,2-15,6)=-9,4
(-2)*(-9,4)=18,8
7,7-(-18,8)=7,7+18,8=26,5
You can use WolframAlpha if you want to verify it
