Calculating the Number of English Textbooks

To calculate the number of English textbooks in the library, we can follow these steps:

1. Calculate the total number of textbooks: - Total number of books = 80,000

2. Calculate the number of textbooks that are textbooks: - Number of textbooks = 9% of 80,000

3. Calculate the number of English textbooks: - Number of English textbooks = 2% of the number of textbooks

Let's calculate the number of English textbooks using the provided percentages.

Calculation

1. Total number of textbooks = 80,000 2. Number of textbooks = 9% of 80,000 3. Number of English textbooks = 2% of the number of textbooks

Solution

1. Total number of textbooks = 80,000 2. Number of textbooks = 9% of 80,000 = 0.09 * 80,000 3. Number of English textbooks = 2% of the number of textbooks = 0.02 * (0.09 * 80,000)

Let's calculate the number of English textbooks.
