Answer:
The difference between the number of pages that Darla and Juan read are VI pages.
Explanation:
Given:
Darla told her teacher that she had read XLV pages in her library book.
Juan said that he had read XXXIX pages.
Now, to get the difference between the number of pages that Darla read and Juan read.
As, we see the number of pages are in roman numeral symbols.
So, we convert them in numbers first to calculate:
Darla read = XLV pages.
Darla read = 45 pages.
Now,
Juan read = XXXIX pages.
Juan read = 39 pages.
So, to get the difference between the number of pages by subtracting:
![45-39=6](https://img.qammunity.org/2021/formulas/mathematics/high-school/tij7wx3fhb68fcxmtyd4iax3u6i722plk6.png)
Thus, the difference between the number of pages = 6 pages.
Now, converting it into roman numerals:
6 pages = VI pages.
Therefore, the difference between the number of pages that Darla and Juan read are VI pages.
