Multipliziere aus

21 (1 - 40 b - 56 c) : 21 - 840 b - 1176 c

= \frac{21 - 840 b - 1176 c}{16}

Wende Bruchregel an:

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

\frac{21 - 840 b - 1176 c}{16} = \frac{21}{16} - \frac{840 b}{16} - \frac{1176 c}{16}

= \frac{21}{16} - \frac{840 b}{16} - \frac{1176 c}{16}

Streiche

\frac{840 b}{16} : \frac{105 b}{2}
