Answer :
Given
[tex]\frac{1}{3}b+\frac{11}{18}[/tex]So, we replace b=1/6 in the previous expression
[tex]\begin{gathered} \frac{1}{3}(\frac{1}{6})+\frac{11}{18} \\ \frac{1\times1}{3\times6}+\frac{11}{18} \\ \frac{1}{18}+\frac{11}{18} \end{gathered}[/tex]Applying fraction properties
[tex]\begin{gathered} \frac{1+11}{18} \\ \frac{12}{18} \end{gathered}[/tex]Simplify
[tex]\frac{2}{3}[/tex]Answer: 2/3
