Question

martin has read 10​% of a book. He has 27 more pages to finish. How many pages are there in the​ book?

Answer 1

Let's start by using algebra to solve the problem.

Let x be the total number of pages in the book.

If Martin has read 10% of the book, that means he has read 0.1x pages.

We know that he has 27 more pages to finish, so the total number of pages he needs to read is 0.9x (since he has already read 0.1x pages).

We can set up the following equation:

0.9x = 27

Solving for x, we get:

x = 30

Therefore, there are 30 pages in the book.
