5 (10 + 330) : 50 + 1530

= - \frac{50 + 15 30}{34}

Wende Bruchregel an:

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

\frac{50 + 15 30}{34} = - (\frac{50}{34}) - (\frac{15 30}{34})

= - (\frac{50}{34}) - (\frac{15 30}{34})

Entferne die Klammern:

(a) = a

= - \frac{50}{34} - \frac{15 30}{34}

\frac{50}{34} = \frac{25}{17}

\frac{15 30}{34} = \frac{15 15}{17 2}

= - \frac{25}{17} - \frac{15 15}{17 2}
