Exercise 25 Page 113

Rewrite each term as a product of the coefficient of the variable term and some other factor.

1/3(b-1)

Practice makes perfect
We want to factor out the coefficient of the variable term — 13. Let's rewrite each term as a product of 13 and some other factor. To do so, note that every number equals itself multiplied by 1. 1{\dfrac{1}{3}b &= {\color{#FD9000}{\dfrac{1}{3}}} \cdot b \\[0.5em] \dfrac{1}{3} &= {\color{#FD9000}{\dfrac{1}{3}}} \cdot 1 } Now we can use the Distributive Property to factor the expression. Let's go!
