4. The Distributive Property

Continue to next subchapter

Exercise 49 Page 30

When distributing, which terms inside the parentheses must be multiplied by the outside term?

Expression: $\frac{1}{3} (27) - 2 b (27)$
Simplified Expression: $9 - 54 b$

Practice makes perfect

Using the Distributive Property, we can multiply each term inside the parentheses by

27 .

(\frac{1}{3} - 2 b) 27

Distribute $27$

\frac{1}{3} (27) - 2 b (27)

Now that we have rewritten the expression, we can simplify our answer.

\frac{1}{3} (27) - 2 b (27)

Multiply

\frac{1}{3} \cdot 27 - 54 b

Rewrite $27$ as $3 \cdot 9$

\frac{1}{3} \cdot 3 \cdot 9 - 54 b

MultFracByInverse

$\frac{a}{b} \cdot \frac{b}{a} = 1$

9 - 54 b
