Given:
Rosa has read 72 pages of a book. These pages make up 45% of the book.

_____________________________________________________________

To find:

The total number of pages in the book.

_____________________________________________________________

Let the total number of books be x,.

Then,

=>45% of x = 72,.

=> \frac{45}{100} x = 72

=>  \frac{9}{20} x = 72

=> x = 72 ( \frac{20}{9} )

=> x = 8(20)

=> x =160,..

∴ There are 160 pages in the book.
