Answer:
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.
