denis-greek [22]

Answer:

1700 books

Step-by-step explanation:

We are given;

  • % of non-fiction books in the library as 28%
  • Number of fiction books in the library as 1,224 books

We are required to determine the total number of books.

First we determine the percentage of non-fiction books

We need to know that;

% of fiction books + % of non-fiction books = 100%

Therefore;

% of non-fiction books = 100 % - 28 %

                                    = 72%

Second we determine the total number of books

We know that;

Total number of books = 100%

But;

72% = 1,224 books

Therefore;

Total number of books = (1,224 × 100%) ÷ 72%

                                      = 1700 books

Hence, the library has a total number of 1700 books
