Question

There were 210 books in a bookstore, 5/7 of the books were fiction books and the rest were non-fiction books. 2/3 of the fiction books and 5/6 of the non-fiction books were in English. How many non-English books were there in the bookstore?

Answer 1

5/7 * 210 = 150 fiction, so 60 non-fiction
2/3 * 150 + 5/6 * 60 = _____ in English
so subtract that number from 210 to get the non-English books

Answer 2

fiction: 5/7 of 210 = 150
non-fiction : 60

English books = (2/3)(150) + (5/6)(60)
= 100+50
= 150

non-English books = 210-150 = 60

Answer 3

Total books in the bookstore = 210
Number of fiction books = 5/7 * 210 = 150
Number of non-fiction books = 210 - 150 = 60
Number of books in English = 2/3 (fiction books) + 5/6 (non-fiction books)
= 2/3 (150) + 5/6 (60)
= 100 + 50
150 books are in English
Number of Non-English books} = Total books - Number of English books
= 210 - 150
= 60 books
