Final answer:
Jenna has 4 1/2 yards of thread which is less than the length of 5 1/4 yards she needs for each piece, so she can't have any complete pieces. There is potentially a mistake in the given information as individual pieces cannot be longer than the total length of thread.
Step-by-step explanation:
The original question states that Jenna has 4 1/2 yards of thread and wishes to cut this into pieces of 5 1/4 yards each. However, it’s impossible for Jenna to cut lengths of 5 1/4 yards from a total length that is shorter, which is only 4 1/2 yards. Thus, there seems to be an error in the problem as posed, since the individual pieces cannot be longer than the total length of thread she has.
To clarify, 4 1/2 yards equals 4.5 yards and each piece is supposed to be 5 1/4 yards, or 5.25 yards. As 4.5 is less than 5.25, it means Jenna cannot cut any complete pieces of the length required. Therefore, based on the information provided, the answer is that Jenna can have 0 complete pieces of thread.
