Answer: There are 18 pages in the Ramal's stamp album.
Step-by-step explanation:
Given: The number of pages filled by Ramal in each stamp album = 3
The part of album filled by Ramal =[tex]\frac{1}{6}[/tex]
Let x be the total number of pages he filled the, we have
[tex]\frac{x}{6}=3[/tex]
Multiply 6 on the both sides , we get
[tex]x=3\times6\\\Rightarrow\ x=18[/tex]
hence, there are 18 pages in the Ramal's stamp album.
