The fraction of fifth-grade students bought at least one book is calculated as 9/16.

Step-by-step explanation:

From the above question:

Fraction of students that went to the book fair = 9/12

Fraction of students that bought at least one book = 6/8

The fraction of fifth-grade students bought at least one book is calculated as:

6/8 of 9/12

= 6/8 × 9/12

= 3/4 × 3/4

= 9/16

Hence, the fraction of fifth-grade students bought at least one book is calculated as 9/16.
