Schritte zur Lösung

\frac{\frac{1}{5} - \frac{5}{4}}{\frac{7}{2} - \frac{3}{4}}

\frac{1}{5} - \frac{5}{4} = - \frac{21}{20}

= \frac{- \frac{21}{20}}{\frac{7}{2} - \frac{3}{4}}

\frac{7}{2} - \frac{3}{4} = \frac{11}{4}

= \frac{- \frac{21}{20}}{\frac{11}{4}}

Wende Bruchregel an:

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

= - \frac{\frac{21}{20}}{\frac{11}{4}}

Wende Bruchregel an:

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

\frac{\frac{21}{20}}{\frac{11}{4}} = \frac{21 \cdot 4}{20 \cdot 11}

= - \frac{21 \cdot 4}{20 \cdot 11}
