Answer: 5 1/3 feet
Step-by-step explanation:
From the question, we are informed that Sarah has a length of curtain material that measures 12 feet and that she cuts a lighthouse of 6 2/3 feet from her curtain material.
To get the length of the remaining piece, we subtract 6 2/3 feet from 12 feet. This will be:
= 12 - 6 2/3
= 5 1/3
The length of the remaining piece is 5 1/3 feet.
