45 because if he had any less, there would be left overs for either the 5 per page or 9 per page.

Lilliana Rowland · Answer 2

45 is the answer

Step-by-step explanation:

The number of baseball cards Bill has is a multiple of 5 and 9. To find the least number of baseball cards, find the LCM of 5 and 9. multiples of 5: 5, 10, 15, 20, 25, 30, 35, 40, 45, ... multiples of 9: 9, 18, 27, 36, 45, ... So, the least number of baseball cards Bill has is 45.
