Question

3. After reading 7/9 of a book, 40 pages are left. How many pages are there in the book?​

Answer 1

Let x be the total pages .

Given number of books =1

7/9 of the book was readed then the remaining book is =1-7/9 =2/9

2/9 = 40

1/9=40/2

1/9=20

So the total book pages = 20 X 9 = 180 pages.
