Answer 3

Calculating the Number of Pages Read

To calculate the number of pages Kolya read in a 240-page book when he has read 0.8 of the book, we can use the following formula:

Number of pages read = Total number of pages in the book × Fraction of the book read

Using this formula, we can calculate the number of pages Kolya read.

The calculation is as follows: Number of pages read = 240 × 0.8

Calculation

The number of pages Kolya read is: Number of pages read = 240 × 0.8 = 192

Therefore, Kolya read 192 pages of the 240-page book.
