Answer 2

Calculating Remaining Pages to Read

To calculate the remaining pages the boy needs to read, we can use the fact that he has already read 3 7/7 parts of the book.

The total number of pages in the book is not provided, so we'll calculate the remaining pages based on the information given.

The calculation can be done as follows:

1. Calculate the total number of pages in the book. 2. Subtract the pages already read from the total to find the remaining pages.

Let's proceed with the calculation:

Step 1: Calculate the total number of pages in the book.

Step 2: Subtract the pages already read from the total to find the remaining pages.

Step 1: Calculate the total number of pages in the book.

We don't have the exact number of pages in the book, but we can calculate it based on the information given.

The boy has read 3 7/7 parts of the book, which can be simplified to 3 1/7 or 22/7 when converted to an improper fraction.

Let's calculate the total number of pages using this information.

Step 2: Subtract the pages already read from the total to find the remaining pages.

We'll use the total number of pages calculated in Step 1 to find the remaining pages.

Let's proceed with the calculation.

Step 2: Subtract the pages already read from the total to find the remaining pages.

We'll use the total number of pages calculated in Step 1 to find the remaining pages.

Let's proceed with the calculation.

22/7 * x = 259

x = 259 / (22/7)

x ≈ 259 / 3.14

x ≈ 82.48

So, the total number of pages in the book is approximately 82.48.

Now, we'll calculate the remaining pages:

Remaining pages = Total pages - Pages already read = 82.48 - 3 ≈ 79.48

Therefore, the boy has approximately 79.48 pages left to read in the book.

This calculation is based on the information provided and the assumption that the book has a total of 259 pages.
