Answer:
Total number of 1 2/3 feet long pieces that will be cut=8 pieces
Step-by-step explanation:
This can be expressed as;
Total length of the board=length per piece×number of pieces
where;
Total length of board=14 1/4 feet
Length per piece=1 2/3 feet
Number of pieces=n
Replacing;
14 1/4=1 2/3×n
(57/4)=(5/3)n
n=(57/4)×(3/5)=8.55
Total number of 1 2/3 feet long pieces that will be cut=8 pieces
