A piece of rope 6.54 metres long is cut
into two pieces. One piece is twice as
long as the other. What is the length of
the longest piece?

Respuesta :

X=shorter piece of rope
2X=longest piece of rope
X+2X=6.54 m
3X=6.54 m
X=6.54/3
X=2.18 m

Shorter piece is 2.18 m long
Longest piece is 2•2.18=4.36 m long
