The carpenters

The carpenters cut the beam. Half of the cut pieces were 1 meter long, a quarter of the pieces were two meters long, and they cut the remaining 8 meters of the beam into two equal parts.
- What was the length of the original beam?
- What part of the original beam was cut into meter pieces?

Correct answer:

a =  16 m
b =  1/4

Step-by-step explanation:

n/2+n/4+2=n  n=8  n=18=8  n=8  d1=n/2 1=8/2 1=4 m d2=n/4 2=8/4 2=4 m d3=8 m  a=d1+d2+d3=4+4+8=16 m
