Answer:

[tex]\frac{9}{16}[/tex]

Step-by-step explanation:

Let total number of students[tex]=x[/tex]

Students went to the book fair:

Students went to book fair[tex]=\frac{15}{20}\times total\ number\ of\ students=\frac{15}{20}x[/tex]

Students who bought book:

[tex]Students\ who\ bought\ book=\frac{12}{16}\times Number\ of\ students\ went\ to\ book\ fair=\frac{12}{16}\times \frac{15}{20}x=\frac{9}{16}x[/tex]

Hence [tex]\frac{9}{16}[/tex] of total students bought at least one book.
