Problem Analysis

The problem states that a boy has read one-third of a 60-page book, and we need to determine how many pages he has left to read.

Solution

To solve this problem, we need to find one-third of 60 and subtract it from the total number of pages in the book.

Calculation

One-third of 60 is calculated by multiplying 60 by 1/3: ``` 1/3 * 60 = 20 ```

So, the boy has read 20 pages of the book.

To find the number of pages he has left to read, we subtract the number of pages he has read from the total number of pages in the book: ``` 60 - 20 = 40 ```

Therefore, the boy has 40 pages left to read.

Answer

The boy has 40 pages left to read in the book.
