Answer 2

Problem Analysis

Sergey filled 5/8 of a notebook with math problems and had 36 blank pages left. We need to determine the total number of pages in the notebook.

Solution

To find the total number of pages in the notebook, we can set up a proportion using the information given. The proportion can be set up as follows:

5/8 = 36/x

Where x represents the total number of pages in the notebook.

To solve for x, we can cross-multiply and then solve for x:

5x = 8 * 36

5x = 288

x = 288 / 5

x = 57.6

Since the number of pages in a notebook cannot be a decimal, we can round up to the nearest whole number. Therefore, the notebook has 58 pages.

Answer

The notebook has 58 pages.
