Final answer:
To find the pages Anna read per hour, divide the fraction of the book she read (4/5) by the time spent (2/3 hour), resulting in reading 4/3 pages per hour.
Step-by-step explanation:
The student's question asks how many pages Anna read per hour if she read 4/5 of her book in 2/3 of an hour.
To find the number of pages read per hour, we will use the unit rate formula, which is the number of pages read divided by the time it took to read those pages in hours.
We calculate the unit rate with the following steps:
- Divide 4/5 (the portion of the book read) by 2/3 (the time taken to read it).
- Multiply the result by 1 hour to find the pages read per hour.
Let's calculate it:
(4/5) ÷ (2/3) = (4×5) ÷ (5×3)
= 4/3 pages
Therefore, Anna read 4/3 pages, or approximately 1.33 pages per hour.
