Question

Olivia has has read 40 pages of a 70 page book, 60 pages of an 85 page book, and 43 pages. What is the percentage f pages that Olivia has not read?

Answer 1

Below

Explanation:

Total pages read = 40 + 60 +43 = 143 pages read

Total pages of all of the books = 70 + 85 + x

percentage READ = (143) / ( 70 + 85 + x) * 100% = ???

percentage NOT read = 100 - ???

(since 'x' was not given in the question post)

Answer 2

Read pages:

40+60+43=143

All pages:

70+85+43=198

198-143=55

55/198=0,2778

0,2778×100%=27.78%
