Calculating Percentage of Books in Foreign Languages

To calculate the percentage of books in the library that are in foreign languages, we can use the following formula:

Percentage of foreign language books = (Number of foreign language books / Total number of books) * 100

Given that 11/20 of the books are in Russian, we can calculate the percentage of books in foreign languages.

Calculation

Using the given information, we can calculate the percentage of books in foreign languages as follows:

Percentage of foreign language books = (Total number of books - Number of Russian books) / Total number of books * 100

Percentage of foreign language books = (20 - 11) / 20 * 100

Percentage of foreign language books = 9 / 20 * 100

Percentage of foreign language books = 45%

Therefore, 45% of all the books in the library are in foreign languages.
