Warren read 1/6 of the pages of a book last Monday. Tuesday he read 2/5 of the remainder of the pages. Wednesday he read 1/3 of the remaining pages. He has 60 more pages left to read. How many pages does the book have?
Total = X pages.
Monday: 1/6 * x = x/6 Pages read.
x-x/6 = 6x/6 - x/6 = 5x/6 Remaining.
Tuesday: 2/5 * 5x/6 = x/3 Pages read.
5x/6 - x/3 = 5x/6 - 2x/6 = 3x/6 Remaining.
Wednesday: 1/3 * 3x/6 = x/6 Pages
3x/6 - x/6 = 2x/6 = x/3 Remaining.
x/3 = 60, X = 180 Pages.
