Final answer:
By dividing the total number of 27 cards by the number of cards per page, which is 9, we find that James uses 3 pages to hold all his cards. Therefore the correct answer is Option A.
Step-by-step explanation:
The subject of this question is Mathematics, specifically dealing with basic division and multiplication in terms of distributing objects (cards) evenly across a set number (pages in a book).
To find out how many pages James will use, we need to divide the total number of cards by the number of cards he puts on each page. James has 27 cards and he puts 9 cards on each page. So, we do the math: 27 ÷ 9 = 3. Therefore, James uses 3 pages to hold all his cards.
The correct answer to the question is a) 3 pages.
