Schritte zur Lösung

\frac{( - \frac{1}{3} ) - 1}{2 ( - \frac{1}{3} ) ^{2} - ( - \frac{1}{3} )}

\frac{( - \frac{1}{3} ) - 1}{2 ( - \frac{1}{3} ) ^{2} - ( - \frac{1}{3} )} = \frac{- \frac{1}{3} - 1}{2 ( - \frac{1}{3} ) ^{2} + \frac{1}{3}}

= \frac{- \frac{1}{3} - 1}{2 ( - \frac{1}{3} ) ^{2} + \frac{1}{3}}

- \frac{1}{3} - 1 = - \frac{4}{3}

= \frac{- \frac{4}{3}}{2 ( - \frac{1}{3} ) ^{2} + \frac{1}{3}}

2 (- \frac{1}{3})^{2} + \frac{1}{3} = \frac{5}{9}

= \frac{- \frac{4}{3}}{\frac{5}{9}}

Wende Bruchregel an:

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

= - \frac{\frac{4}{3}}{\frac{5}{9}}

Wende Bruchregel an:

\frac{\frac{a}{b}}{\frac{c}{d}} = \frac{a \cdot d}{b \cdot c}

\frac{\frac{4}{3}}{\frac{5}{9}} = \frac{4 \cdot 9}{3 \cdot 5}

= - \frac{4 \cdot 9}{3 \cdot 5}
