Calculation of Percentages

To calculate the percentages, we need to determine the ratio of the given quantity to the total quantity and then multiply it by 100.

1. 3 people out of 12: The percentage of 3 people out of 12 can be calculated as (3/12) * 100 = 25%. Therefore, 3 people constitute 25% of 12.

2. 10 rubles out of 800: The percentage of 10 rubles out of 800 can be calculated as (10/800) * 100 = 1.25%. Therefore, 10 rubles constitute 1.25% of 800.

3. 4 textbooks out of 160 books: The percentage of 4 textbooks out of 160 books can be calculated as (4/160) * 100 = 2.5%. Therefore, 4 textbooks constitute 2.5% of 160.

4. 24 correct answers out of 32 questions: The percentage of 24 correct answers out of 32 questions can be calculated as (24/32) * 100 = 75%. Therefore, 24 correct answers constitute 75% of 32.

5. 2 correct answers out of 32 questions: The percentage of 2 correct answers out of 32 questions can be calculated as (2/32) * 100 = 6.25%. Therefore, 2 correct answers constitute 6.25% of 32.

6. 9 hits out of 10 shots: The percentage of 9 hits out of 10 shots can be calculated as (9/10) * 100 = 90%. Therefore, 9 hits constitute 90% of 10.

Please note that the percentages are rounded to two decimal places for simplicity.
