Answer 1

The number of students who liked the book was 64.

Explanation:

After reading a book for English class, 100 students were asked whether or not they enjoyed it.

Now, given that nine twenty-fifths of the class did not like the book.

So,
`(9)/(25)` of the whole class did not like the book.

Then, the fraction of the class who did like the book was
`(1 - (9)/(25)) = (16)/(25)`.

Therefore, the number of students who liked the book was
`(100 * (16)/(25)) = 64`. (Answer)
