36/4=9 дней

Answer 3

Problem Statement

В одной книге 12 страниц, а во второй - 24. За сколько дней можно прочитать обе книги, если ежедневно читать 4 страницы?

Solution 1: Using Basic Arithmetic

To solve this problem, we can use basic arithmetic to calculate the number of days required to read both books.

Let's break down the problem step by step:

1. Calculate the total number of pages in both books: 12 + 24 = 36 pages. 2. Determine the number of pages read per day: 4 pages. 3. Divide the total number of pages by the number of pages read per day to find the number of days required: 36 / 4 = 9 days.

Therefore, it would take 9 days to read both books if you read 4 pages per day.

Solution 2: Using Division and Ceiling Function

Another way to solve this problem is by using division and the ceiling function. The ceiling function rounds up a number to the nearest whole number.

Let's break down the problem step by step:

1. Calculate the total number of pages in both books: 12 + 24 = 36 pages. 2. Determine the number of pages read per day: 4 pages. 3. Divide the total number of pages by the number of pages read per day and round up using the ceiling function: ceil(36 / 4) = ceil(9) = 9 days.

Using this method, we also find that it would take 9 days to read both books if you read 4 pages per day.

Note: Both solutions yield the same result of 9 days.
