Question

Madison read 1/2 of a book in the morning, and she read some more at night. By the end of the day she still had 2/5 of the book left to read. How much of the book did Madison read at night?​

Answer 1

Answer: 1/10

Explanation:

At the end of the day, she still had 2/5 of the book to read. Which meant that she had read 3/5 of the book. Since she read 1/2 of the book in the day, we would read 3/5 - 1/2 = 6/10 - 5/10 = 1/10 of the book at night.
