Question

Секретарь напечатал 0,5 всех страниц документа. Когда он набрал 0,7 страниц, то ему осталось напечатать 6 страниц. Сколько страниц в документе?

Answer 1

6 страниц это 1 - 0,7 = 0,3 всей работы секретаря
Тогда вся работа составит: 6:0,3 = 20 страниц
Всего страниц в рукописи в два раза больше(один секретарь делает 0,5(половину) всей работы) = 20 * 2 = 40 страниц

Answer 2

Calculating the Number of Pages in the Document

To solve this problem, we can set up a simple equation based on the given information.

Let's denote the total number of pages in the document as x.

According to the given information: - The secretary printed 0.5 * x pages of the document. - When the secretary printed 0.7 pages, 6 pages were left to print.

We can express this information in the form of an equation and solve for x.

Solution

We can set up the equation as follows: 0.5x + 0.7 = x - 6

Now, let's solve for x.

0.5x + 0.7 = x - 6 0.7 + 6 = x - 0.5x 6.7 = 0.5x x = 6.7 / 0.5 x = 13.4

Answer

The document consists of 13.4 pages.

This means that the document consists of 13 full pages and 0.4 of another page.
