Gabriel Macduff - 29.01.2016 01:11Percentage of pages of a book read by Alexander = 43% Total number of pages of the book read by Alexander = 129 Let us assume the number of pages that the book has = x Then (43/100) * x = 129 43x = 129 * 100 43x = 12900 x = 12900/43 = 300 So the book has a total of 300 pages in it. Then The number of pages that Alexander still needs to read = 300 - 129= 171 So Alexander needs to read 171 more pages in the book.
