Answer: -35.375 or -283/8

Step-by-step explanation:

Begin with the parenthese: (-1.5+9.5)=8 and (7+11)

Then you have 5/8+0.4(18)/-0.2.

Multiply 0.4 times that 18 and you get 7.2.

Then you have 5/8+7.2/-0.2

Simplify 7.2/-0.2 which equals -36

Then you have 5/8+-36

5/8+-36=-35.375 or in fraction form -283/8
