Find the least common denominator for these two rational expressions. B/b^2 -64 -7b/b^2+7b-8

san4es73 [151]

Answer:

The least common denominator is (b-8)(b+8)(b-1)

Step-by-step explanation:

We are given expression as

$\frac{b}{b^2-64}-\frac{7b}{b^2+7b-8}$

Firstly, we will factor both denominators

$b^2-64=b^2-8^2=(b-8)(b+8)$

$b^2+7b-8=(b+8)(b-1)$

so, we can plug it back

$\frac{b}{(b-8)(b+8)}-\frac{7b}{(b+8)(b-1)}$

First term denominator is

(b-8)(b+8)

Second term denominator is

(b+8)(b-1)

So,

Least common denominator will be

(b-8)(b+8)(b-1)

So, we get

$LCD=(x-8)(x+8)(x-1)$

84 2/3% to a fraction in lowest terms

RoseWind [281]

The evaluation of 84 2/3% to a fraction in its lowest term is $\mathbf{ \dfrac{127}{150} }$

<h3>What is a fraction?</h3>

Fractions are sections or parts of a whole. They are divided into two parts, the numerator, and the denominator.

From the given information, we are to convert a mixed fraction into its lowest terms. By doing that, we are to convert it to an improper fraction.

$\mathbf{= 84 \dfrac{2}{3}\%}$

$\mathbf{= \dfrac{(84 \times 3)+2}{3} \%}$

$\mathbf{= \dfrac{254}{3} \%}$

$\mathbf{= \dfrac{254}{3} \times \dfrac{1}{100}}$

$\mathbf{= \dfrac{254}{300} }$

Divide both the numerator and denominator by (2)

$\mathbf{= \dfrac{127}{150} }$
