Nov 30, 2016

$x \approx 34.2$

#### Explanation:

Let's call the unknown number $x$.
Write an equation to show what is given..

79% of some number is equal to $27.0$
$\downarrow \textcolor{w h i t e}{. .} \downarrow \textcolor{w h i t e}{\ldots \ldots .} \downarrow \textcolor{w h i t e}{\ldots \ldots \ldots . .} \downarrow \textcolor{w h i t e}{\ldots \ldots \ldots} \downarrow$

79% xx color(white)(.........)x color(white)(............)=color(white)(........) 27.0

$\frac{79}{100} \times x = 27 \text{ } \leftarrow$ solve for $x$

$x = 27.0 \times \frac{100}{79}$

$x = 34.1772$
