Final answer:
Allison had 5 yards on a spool and used 2 meters. After converting yards to meters, she has approximately 2.572 meters of thread left on the spool.
Step-by-step explanation:
The student, Allison, is dealing with a conversion problem between different units of length. Initially, she has a spool of thread measuring 5 yards, and after using 2 meters of it, we want to determine how much is left, in meters. First, we need to know that 1 yard is approximately 0.9144 meters. Using this conversion factor, we can calculate the total initial length in meters:
5 yards * 0.9144 meters/yard = 4.572 meters
Next, since Allison uses 2 meters from the spool:
4.572 meters - 2 meters = 2.572 meters
Therefore, approximately 2.572 meters of thread is left on the spool. This answer is already precise to the nearest thousandth, so no additional rounding is necessary.
