Question

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

Answer 1

it is 170 pages

Explanation:

you change 32% to a fraction 32/100 then figure the rest out cause the rest of it is mental math.

Answer 2

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.
