I di try and answer them on my own and got A) 22 7/36 yards of rope.
B) 22 pieces
C) 7/12 of the rope was left.
Please help, are these correct?
If not can you explain and help me understand the question. Thanks
a) correct
b)
from the 15 1/3 ft piece we can cut 5 pieces of 3 ft, leaving 1/3 ft
from the 20 1/2 ft piece we can cut 6 pieces of 3 ft, leaving 2 1/2 ft
from the 30 3/4 ft piece we can cut 10 pieces of 3 ft leaving 3/4 ft
so we can cut 5+6+10 or 21 pieces of 3 ft each
c) amount left over:
1/3 + 2 1/2 + 3/4
= 3 7/12 ft
for partB) since for each part that was left was more than 3 feet as you see in part C won't that be added as one more foot making the answer to B) 22 pieces
and part C) 7/12 left?
I read the question to mean that you want complete 3 ft sections, not pieces that have been tied together to make 3 ft.
from a piece of 20 1/4 ft, I can only get 6 sections of 3 ft, even though a big piece would be left over.
Let's agree it is a poorly worded question.
