Answer 3

Calculation of the Number of Math Textbooks

To determine the number of math textbooks purchased by the school library, we need to calculate 38% of the total number of textbooks.

Given: - Total number of textbooks purchased: 150 - Percentage of Russian language textbooks: 62%

To find the number of math textbooks, we can subtract the number of Russian language textbooks from the total number of textbooks and then calculate 38% of that result.

Let's calculate it step by step:

1. Calculate the number of Russian language textbooks: - 62% of 150 textbooks = 0.62 * 150 = 93 textbooks

2. Calculate the number of math textbooks: - Total textbooks - Russian language textbooks = 150 - 93 = 57 textbooks

Therefore, the school library has purchased 57 math textbooks.

Please note that the calculations are based on the given information and assumptions made.
