Answer: " -54b + 9 " .
___
Explanation:
Note the distributive property of multiplication:
 a(b + c) = ab + ac ; 
We are given: (1/3 − 2b)27 ; 
Let's rewrite: ↔ 27(1/3 − 2b) ; 
Now: Rewrite using the distributive property. Then, simplify.
 27 (1/3 − 2b) = (27 * 1/3) + (27 * -2b) ; 
 = 9  + (-54)b ; 
 ↔ = - 54b + 9 ; 
 → which is the simplified form of the expression.
