hello
the expression given is
[tex](\frac{1}{3}-2b)27[/tex]now we rewrite the equation using distributive property
[tex](a+b)\times c=(a\times c)+(b\times c)_{}[/tex][tex]\begin{gathered} (\frac{1}{3}-2b)\times27 \\ (27\times\frac{1}{3})+(-2b\times27) \\ 9-54b \end{gathered}[/tex]the expression is 9 - 54b
