Katie has read 32 % of a book. If she has read 80 pages, how many more pages does Katie have left to read?

Percentage of pages of a book read by Katie = 32%

Total number of pages of the book read by Katie = 80

Let us assume the number of pages that the book has = x

Then

(32/100) * x = 80

32x = 80 * 100

32x = 8000

x = 8000/32

= 250

So the book has a total of 250 pages in it.

Then

The number of pages that Katie still needs to read = 250 - 80

= 170

So Katie needs to read 170 more pages in the book.
