Answer 1

`(9)/(16)`

Explanation:

Out of a total of 1,
`(15)/(20)` went to the fair and
`(12)/(16)` OF THOSE, bought atleast one book.

To find the fraction of students who bought at least one book, we will multiply both the fractions. That is the answer. Shown below:

`(15)/(20)*(12)/(16)\\=(3)/(4)*(3)/(4)\\=(9)/(16)`

Answer is
`(9)/(16)`
