Question

В первой библиотеке 12000 книг, а во второй - 75% этого количества. Сколько книг в двух библиотеках вместе?

Answer 1

(12000:100)*75=9000 - во 2 библиотеке
12000+9000=21000 - в 2-х библиотеках

Answer 2

Я могу помочь вам с вашим вопросом.

Чтобы решить эту задачу, нам нужно знать, сколько книг во второй библиотеке. Мы можем найти это число, умножив 12000 на 0.75, потому что 75% равно 0.75. Это даст нам 9000 книг во второй библиотеке.

Теперь, чтобы найти общее количество книг в двух библиотеках, нам нужно сложить 12000 и 9000. Это даст нам 21000 книг в двух библиотеках вместе.

Ответ: В двух библиотеках вместе 21000 книг.

Calculating the Total Number of Books in Two Libraries

To calculate the total number of books in the two libraries, we can follow these steps:

1. Calculate the number of books in the second library. 2. Add the number of books in the first library to the number of books in the second library.

Step 1: Calculate the Number of Books in the Second Library

The second library contains 75% of the number of books in the first library. Given that the first library has 12,000 books, we can calculate the number of books in the second library using the following formula:

Number of books in the second library = 75% of 12,000

Using the formula, we can calculate the number of books in the second library: ``` Number of books in the second library = 0.75 * 12000 ``` Number of books in the second library = 9,000

Step 2: Calculate the Total Number of Books in Both Libraries

Now, we can calculate the total number of books in both libraries by adding the number of books in the first library to the number of books in the second library:

Total number of books = Number of books in the first library + Number of books in the second library

Plugging in the values: ``` Total number of books = 12,000 + 9,000 ``` Total number of books = 21,000

Answer:

The total number of books in both libraries together is 21,000.
