Question

I need a tutor very smart to answer this question

Answer 1

Given the expression :

`(1)/(3)b+(2)/(3)b-(5)/(6)(b+1)=?`

The expression will be equal:

`\begin{gathered} (1)/(3)b+(2)/(3)b-(5)/(6)b-(5)/(6) \\ \\ =((1)/(3)b+(2)/(3)b-(5)/(6)b)-(5)/(6) \\ \\ =(1)/(6)b-(5)/(6) \end{gathered}`

so, the answer is option 4)

`(1)/(6)b-(5)/(6)`
