vereinfachen ((-42/13))/((-7/26))

Lösung

vereinfachen

\frac{( - \frac{42}{13} )}{( - \frac{7}{26} )}

12

Schritte zur Lösung

\frac{- \frac{42}{13}}{- \frac{7}{26}}

Wende Bruchregel an:

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

= \frac{\frac{42}{13}}{\frac{7}{26}}

Wende Bruchregel an:

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

= \frac{42 \cdot 26}{13 \cdot 7}

Streiche

\frac{42 \cdot 26}{13 \cdot 7} : 12

= 12

2 (x + 3)^{2} = 40

\frac{2}{7} x = 10

x^{2} - 6 x - 6 = 0

\frac{1}{3} m - 5 = - 6

x + x + 5 = 90
