Problem Analysis

Vasya is reading a book that has 480 pages. After reading for four days, he has 120 pages left to read. We need to calculate the percentage of the book that Vasya has already read.

Solution

To find the percentage of the book that Vasya has already read, we can use the following formula:

Percentage = (Number of pages read / Total number of pages) * 100

Let's calculate the percentage.

Calculation

The total number of pages in the book is 480. The number of pages Vasya has left to read is 120.

The number of pages Vasya has already read can be calculated by subtracting the number of pages left to read from the total number of pages:

Number of pages read = Total number of pages - Number of pages left to read

Substituting the values:

Number of pages read = 480 - 120 = 360

Now, we can calculate the percentage:

Percentage = (Number of pages read / Total number of pages) * 100

Substituting the values:

Percentage = (360 / 480) * 100 = 75%

Answer

Vasya has already read 75% of the book.
