hiroshi borrowed 3 non ficktion books from the library. This was 25% of the books he checked out. How many books did Hiroshi check out?

25% ---> 1/4

(1/4)x = 3
x = 12

To find the total number of books Hiroshi checked out, we can set up an equation using the given information. Let's denote the total number of books he checked out as "x."

According to the problem, Hiroshi borrowed 3 non-fiction books, which is 25% of the total books he checked out. This can be represented as:

3 = 0.25x

To find the value of x, we need to solve this equation for x. We can start by dividing both sides of the equation by 0.25:

3 ÷ 0.25 = x

This simplifies to:

12 = x

So, Hiroshi checked out a total of 12 books from the library.
