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
