expand ((n-2)*180)/n

Solution

expand

\frac{( n - 2 ) \cdot 180}{n}

Solution

180 - \frac{360}{n}

Solution steps

\frac{( n - 2 ) \cdot 180}{n}

Expand

(n - 2) \cdot 180 : 180 n - 360

= \frac{180 n - 360}{n}

Apply the fraction rule:

\frac{a \pm b}{c} = \frac{a}{c} \pm \frac{b}{c}

\frac{180 n - 360}{n} = \frac{180 n}{n} - \frac{360}{n}

= \frac{180 n}{n} - \frac{360}{n}

Cancel

\frac{180 n}{n} : 180

= 180 - \frac{360}{n}
