Including a 6% sales tax, an inn charges $155.82 per night. Find the inn's nightly cost before tax is added.

Feliz [49]

we know the Inn is charging 155.82 and that's 100% plus 6%, namely 106% of an amout of say that is "x", being the 100%.

since we know that 155.82 is 106%, what is "x"?

$\begin{array}{ccll} amount&\%\\ \cline{1-2} 155.82&106\\ x&100 \end{array}\implies \cfrac{155.82}{x}=\cfrac{106}{100}\implies \cfrac{155.82}{x}=\cfrac{53}{50} \\\\\\ 7791=53x\implies \cfrac{7791}{53}=x\implies 147=x$

What is the common denominator of StartFraction 1 Over a EndFraction StartFraction 1 Over b EndFraction in the complex fraction

stepladder [879]

The common denominator is 1

Given the expression:

$\frac{1/a-1/b}{1/a1/b}$

Find the LCM of the numerator to have:

$\dfrac{\frac{b-a}{ab} }{\frac{1}{a} \frac{1}{b} }$

Simplify both the numerator and the denominator to have:

$= \dfrac{\frac{b-a}{ab} }{\frac{1}{ab} }\\= \frac{b-a}{ab} \times ab\\=\frac{b-a}{1} \times 1 \\=\frac{b-a}{1}$

From the result, we can see that the common denominator is 1
