Find the least common denominator for these two rational expressions

kogti [31]

factor the 2 denominators:-

a^2 - 6a + 9 = (a - 3)(a - 3)

a^2 - 8a + 15 = (a - 3)(a - 5)

((a - 3) is common to both sets of factors so the LCD is:-

(a - 3)(a - 3)(a - 5) or this can be written as (a -3)^2(a - 5)

Mira has breakfast at a restaurant. She leaves a 20% tip of $1.80.

lutik1710 [3]

let's say the breakfast price was "x", so that's the 100%, and we know she gave 20% of that and that is 1.80.

so, 1.80 is 20%, and "x" is the 100%, what is "x"?

$\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 1.80&20\\ x&100 \end{array}\implies \cfrac{1.80}{x}=\cfrac{20}{100}\implies \cfrac{1.8}{x}=\cfrac{1}{5} \\\\\\ 9.0=x\implies 9=x$
