Given:
Total number of cards in the binder = 625
Each page in the binder holds 9 cards.
To find:
The number of pages in the binder that can be COMPLETELY filled.
Solution:
We know that,
[tex]\text{Number of pages filled}=\dfrac{\text{Total cards}}{\text{Cards in each page}}[/tex]
Putting the given values, we get
[tex]\text{Number of pages filled}=\dfrac{625}{9}[/tex]
[tex]\text{Number of pages filled}=69.44...[/tex]
Approximate the value to the preceding whole number to get the number of pages in the binder that can be COMPLETELY filled.
[tex]\text{Number of pages filled}=69[/tex]
Therefore, 69 pages of binder are completely filled.
