Question
Michael has read 3/4 of a book, while Anna has read
only 2/3 of the book she is reading. Both, however, have another 90 pages of their respective books remaining to be read. What fraction of the number of pages read by Michael has been read by Anna?Solution
Michael has read a book. Remaining for Michael = 1-3/4= 3/4 Anna has read 2/3 of a book. Remaining for Anna = 1-2/3 = 1/3 For Michael: 1/4 = 90 pages, so total pages = 360 pages For Anna: 1/3= 90 pages, so total pages = 270 pages Pages read by Anna compared to Michael: =180/360 =2/3
