Mauro hat 140ft Seil. Er wird es in zwei Stücke schneiden, so dass die Länge des längeren Stücks das Dreifache der Länge des kürzeren Stücks beträgt. Wie lang wird das längere Stück sein?

Hello Guest!

The longer piece of rope is x.

$$\frac{x}{3}+x=140\ |form\ the\ same\ divisor\\ \frac{x+3x}{3}=140\ | * 3 \\ x+3x=140\cdot 3\ |calculate \\ 4x=420\ | : 4 \\ \color{blue}x=105$$

The length of the longer piece is 105ft.
