Final answer:
Without specific data on Mrs. Ali's paper collection and usage, it's impossible to accurately determine the fraction of paper used. However, one would typically divide the quantity of used paper by the total to find the fraction representing the paper used, under normal circumstances.
Step-by-step explanation:
The question regarding Mrs. Ali's notebook paper usage over three months involves understanding and working with fractions. Unfortunately, without the full context or numerical data indicating how much paper was collected and how much was used during these three months, we cannot accurately determine which fraction represents the used paper.
However, we can discuss strategies for handling similar problems. Using fractions, we can express parts of a whole. If we know the total amount of notebook paper collected by Mrs. Ali and the amount used within the specified time frame, we can then divide the used quantity by the total quantity to ascertain the fraction representing the paper used.
For instance, if Mrs. Ali had collected 8 notebooks and 2 were used in three months, we would have used 2 out of 8 notebooks, which simplifies to 1/4 of the total notebooks. Similarly, if 7 out of 8 notebooks were used, this would be 7/8 of the total collection. The understanding of fractions is crucial in solving these types of problems.
