50 pages
Explanation:
Kevin has 450 cards , and each page of the album holds 9 cards. Which means, if each page holds 9 cards; One page will hold 9 cards, the second page, another 9 cards and so on.
Hence, 2 pages will hold 9+9 cards which is 18 cards. 3 pages will hold, 9+9+9= 27 cards
Now, to get how much pages will hold 450 cards, we divide 450 by 9.
450/9= 50 pages
