Question

Tim has read 40% 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 for the total number of pages in the book.

If Tim has read 40% of the book, then he has 60% of the book left to read (100% - 40% = 60%). We can express this as:

0.6x = 27

where x is the total number of pages in the book.

To solve for x, we can divide both sides of the equation by 0.6:

x = 27 ÷ 0.6

x = 45 ÷ 0.01

x = 4500
there are 4500 pages in the book.
