Answer: 25 : 12
25 non-fiction for every 12 fiction
Explanation:
To find the ratio of non-fiction books to fiction books checked out, first, determine how many non-fiction books were checked out.
Total books checked out = 37
Fiction books checked out = 12
To find the number of non-fiction books:
Non-fiction books = Total books - Fiction books
Non-fiction books = 37 - 12
Non-fiction books = 25
Now, you can calculate the ratio of non-fiction books to fiction books:
Ratio = Non-fiction books / Fiction books
Ratio = 25 / 12
This ratio cannot be simplified further because 25 and 12 do not have a common divisor other than 1. So, the ratio of non-fiction books to fiction books checked out is 25:12.
