vereinfachen 3/4 x+0.25(x-6)+28.4

Lösung

vereinfachen

\frac{3}{4} x + 0.25 (x - 6) + 28.4

x + \frac{269}{10}

Schritte zur Lösung

\frac{3}{4} x + 0.25 (x - 6) + 28.4

Schreibe

0.25 (x - 6)

um:

0.25 x - 1.5

= \frac{3}{4} x + 0.25 x - 1.5 + 28.4

0.25 = \frac{1}{4}

= \frac{3}{4} x + \frac{1}{4} x - 1.5 + 28.4

1.5 = \frac{3}{2}

= \frac{3}{4} x + \frac{1}{4} x - \frac{3}{2} + 28.4

28.4 = \frac{142}{5}

= \frac{3}{4} x + \frac{1}{4} x - \frac{3}{2} + \frac{142}{5}

\frac{3}{4} x = \frac{3 x}{4}

\frac{1}{4} x = \frac{x}{4}

= \frac{3 x}{4} + \frac{x}{4} - \frac{3}{2} + \frac{142}{5}

Füge zusammen:

\frac{3 x}{4} + \frac{x}{4} - \frac{3}{2} + \frac{142}{5} : x + \frac{269}{10}

= x + \frac{269}{10}
