Solution steps

\frac{π}{12} - π

Convert element to fraction:

π = \frac{π 12}{12}

= \frac{π}{12} - \frac{π 12}{12}

Since the denominators are equal, combine the fractions:

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

= \frac{π - π 12}{12}

Add similar elements:

π - 12 π = - 11 π

= \frac{- 11 π}{12}

Apply the fraction rule:

\frac{- a}{b} = - \frac{a}{b}

= - \frac{11 π}{12}
