Chapter 7: Q. 167 (page 680)

In the following exercises, simplify each complex rational expression by using the LCD.
$\frac{\frac{1}{3} + \frac{1}{8}}{\frac{1}{4} + \frac{1}{12}}$

Short Answer

Expert verified

The simplified expression is $\frac{11}{8}$ .

Step by step solution

01

Step 1. Given Information.

We have:

$\frac{\frac{1}{3} + \frac{1}{8}}{\frac{1}{4} + \frac{1}{12}}$

02

Step 2. Simplify the numerator.

The numerator is $\frac{1}{3} + \frac{1}{8}$ .

The least common divisor (LCD) of $3, 8$ is $24 .$

Adjust the fractions based on the LCD:

$= \frac{8}{24} + \frac{3}{24} = \frac{8 + 3}{24} = \frac{11}{24}$

03

Step 3. Simplify the denominator.

The denominator is $\frac{1}{4} + \frac{1}{12}$ .

The least common divisor (LCD) of $4, 12$ is $12 .$

Adjust the fractions based on the LCD:

$= \frac{3}{12} + \frac{1}{12} = \frac{3 + 1}{12} = \frac{4}{12} = \frac{1}{3}$

04

Step 4. Substitute the simplified numerator and denominator into the original expression.

We have:

$\frac{\frac{1}{3} + \frac{1}{8}}{\frac{1}{4} + \frac{1}{12}} = \frac{\frac{11}{24}}{\frac{1}{3}}$

Apply fraction rule: $\frac{\frac{a}{b}}{\frac{c}{d}} = \frac{a 路鈥� d}{b 路鈥� c}$

$= \frac{11 路鈥� 3}{24 路鈥� 1} = \frac{11}{8}$
