We have been given that the library has 5 mystery books on a shelf. It has 4 times as many fiction books on another shelf. We are asked to find number of fiction books on the shelf.
The number of fiction books will be 4 times the mystery books.
[tex]\text{Number of fiction books}=4\times \text{ Mystery books}[/tex]
[tex]\text{Number of fiction books}=4\times 5[/tex]
[tex]\text{Number of fiction books}=20[/tex]
Therefore, there are 20 fiction books on the shelf.
