Exercise 26 Page 113

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

3/8(d+2)

Practice makes perfect
We want to factor out the coefficient of the variable term — 38. Let's rewrite each term as a product of 38 and some other factor. To do so, note that 34 is 2 times 38 because 0.75 is 2 times 0.375. 1{\dfrac{3}{8}d &= {\color{#FD9000}{\dfrac{3}{8}}} \cdot d \\[0.5em] \dfrac{3}{4} &= {\color{#FD9000}{\dfrac{3}{8}}} \cdot 2 } Now we can use the Distributive Property to factor the expression. Let's go!
3/8d + 3/4
