Question

Deborah has 104 baseball cards. She gave 16 baseball cards to her brother Corey. Then she put the remaining baseball cards in an album with 9 baseball cards on each page. How many pages of the album did Deborah use to store all of the baseball cards? Explain your thinking

Deborah used 10 pages

104-16=89

89 divided by 9 is 9.89

so Deborah filled 9 full pages and 89% of a 10th page

therefore, she used 10 pages
