Answer 1

Given

Answer

Option 2, 4, and 5 are true

Option 2

`\begin{gathered} 9(2)/(3)-4(1)/(2)=(29)/(3)-(9)/(2) \\ =(31)/(6)=5(1)/(6) \end{gathered}`

Option 4

`\begin{gathered} 4(1)/(2)+(7(2)/(5)-2(3)/(10))=(9)/(2)+((37)/(5)-(23)/(10)) \\ =(9)/(2)+(51)/(10) \\ =(48)/(5)=9(3)/(5) \end{gathered}`

Option 5

`\begin{gathered} 4(1)/(2)-(1(1)/(8)+2(3)/(5)) \\ =(9)/(2)-((9)/(8)+(13)/(5)) \\ =(9)/(2)-(149)/(40) \\ =(31)/(40) \end{gathered}`
