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

Explanation:

x=total number of pages.

1)we calculate the total number of pages.

32% of x =80

(32/100)x=80

x=(80*100)/32

x=250.

2) we calculate the number of pages don´t read.

number of pages don´t read=250-80=170

Answer: 170 pages.

Answer 2

Hi

100%-32% = 68%

32% ⇒ 80 pages
68% ⇒ x pages

32x = 80·(68)
32x = 5440
x = 5440/32
x = 170 pages left to read

Answer: 170 pages
